Fountain
of youth? Study finds new anti-ageing compound in plant
In Japan, the slightly bitter leaves of the Ashitaba plant have long been considered healthy, and a new study has found the traditional belief may have good scientific grounds.
A natural substance in the plant appears to induce a key process that helps remove the "cellular garbage" that can build up as cells age and cause a range of diseases and disorders.
"It is always nice to find a scientific rationale for traditional medical folk tales," said Frank Madeo, a professor at the University of Graz's Institute of Molecular Biosciences, in Austria.
Madeo, who helped lead the research, said the substance known as 4,4'-dimethoxychalcone or DMC, which occurs naturally in Ashitaba plants, induces a process called autophagy.
"This is a cleansing and recycling process," he told AFP. It removes "superfluous material, especially cellular garbage like aggregated proteins."
That "cleaning" process is key to sustained good health as the body ages. When cells fail to promptly and efficiently remove damaged parts, they can build up and that can lead to diseases including cancer.
There are already a handful of compounds known to scientists that work to stimulate the cleaning process. Fasting also appears to naturally encourage cells to undertake spring cleaning.
But in a bid to expand the field of compounds able to protect cells and turn back the hands of time, the team of researchers turned to a class of substances called flavonoids.
Many flavonoids have already been shown to have a range of beneficial effects, ranging from anti-inflammatory properties to protecting against brain degeneration and cancer.
The team reasoned that they might find flavonoids that could also help prevent destructive ageing in cells.
They screened 180 compounds representing various subcategories of flavonoids, looking for candidates that might have the natural ability to "counteract age-related cell demise."
- Cell-protective capacity -
After initial screening, they settled on DMC and started by testing how the substance affected yeast cells.
They discovered it was indeed helping to protect the yeast cells from the effects of ageing, and that the substance performed as well or even better than some existing compounds prized for their cell-protective capacity like resveratrol, which occurs in grape skin, among other places.
The team then tested DMC's effect on cells in both worms and fruit flies -- common test subjects in medical research.
"Remarkably, chronic DMC treatment... prolonged the median lifespan of both model organisms by approximately 20 percent," the study published Wednesday in the Nature Communications journal says.
Additional tests showed the compound helped protect cells in mice hearts through the autophagy process, and even protected against a kind of liver damage caused by ethanol intoxication.
The team also tested DMC's effect on several types of human cells and found that there too the substance worked to slow ageing.
"The experiments indicate that the effects of DMC might be transferable to humans, although we have to be cautious and wait for real clinical trials," said Madeo.
The research is still in the early stages and Madeo said next steps will include testing whether the positive effects of DMC in mice hearts extend more broadly to protect mice against ageing and age-related diseases.
"Eventually, clinical trials on humans are needed," he added.

Ashitaba
Angelica keiskei, commonly known under the Japanese name of ashitaba (アシタバ or 明日葉), literally "tomorrow's leaf", is a species of flowering plant in the carrot family. It is native to Japan, where it is found on the Pacific Coast.[1] It is endemic to the area of the Bōsō Peninsula, Miura Peninsula, Izu Peninsula, and the Izu Islands. It has been widely cultivated outside its natural range.
Scientific classification edit
Kingdom: Plantae
Clade: Angiosperms
Clade: Eudicots
Clade: Asterids
Order: Apiales
Family: Apiaceae
Genus: Angelica
Species: A. keiskei
Binomial name
Angelica keiskei
Description
It is a perennial, with a typical growth height of 50–120 cm. Like most other members of the carrot family, it produces large umbels of white flowers and has dissected leaves.
Angelica keiskei closely resembles Angelica japonica, but can be distinguished by its blooming period, which lasts from May to October, whereas A. japonica's blooming period lasts only between May and July. Another indicator is the characteristic color of its sap.[2]
Taxonomy
This species is named in honor of Keisuke Ito, a Japanese physician and biologist. A named cultivar of this species, "Koidzumi", refers to botanist Gen'ichi Koizumi. The Japanese name of Angelica keiskei, "ashitaba", stems from the above-average regenerative capabilities it exhibits after injury.
Cultivation
Many Japanese plant ashitaba in herb gardens, flower pots, and backyards. This is due to the modest conditions for cultivation and fast rate of growth. This is a cold hardy plant, with optimal temperatures ranging between 12 and 22 °C. Harvesting a leaf at the break of day often results in a new sprout growing overnight, being visible the following morning.
Uses
As food
The main use of their stipes, leaves, and taproots is in regional cuisine, where they are prepared as soba, tempura, shōchū, tea, ice cream, pasta, etc. The 'Mikura-jima' variety might excel in this regard as it is reputed to be less bitter than others.[3]
As medicine
A. keiskei has been claimed to exhibit cytotoxic, antidiabetic, antioxidative, anti-inflammatory, antihypertensive, and antimicrobial properties via in vitro studies, but the efficacy of these qualities have not been confirmed in vivo.[4]
Historical use
Traditionally, it is seen as a major contributor to the supposedly healthier, extended lives of the local residents, possibly due to the chalconoids that are unique to this species of Angelica. At one point in Edo period, the haulm's yellow sap was effectively used in the external treatment of smallpox, which prompted Kaibara Ekken to describe the herb in his Yamato honzō (大和本草), under the name of ashitagusa (鹹草), as "a powerful tonic drug." In folk medicine, it is claimed to be diuretic, tonic, to improve digestion, and when applied topically, to speed wound healing and prevent infection. Also, its nutritive qualities are said to be the factor behind the internal exiles and their families' never waning stamina in the face of their arduous compulsory labor.
For similar reasons, it very widely serves as pasture for cattle, reckoned to improve the quality of milk, as well as the yield and to maintain cattle health at the same time. Most of these claims have yet to be proven in trials, while studies have substantiated the presence of furocoumarins in several of these plants' components. Furanocumarin is known to increase skin sensitivity to sunlight and may cause dermatitis.
Claims of vitamin B12 source
Although it is often suggested that A. keiskei is a vegetable source of vitamin B12 (cobalamin), recently published, peer-reviewed scientific investigations of pharmacology and phytochemical constituents of interest report nothing that substantiates this claim.[5][6] Traditional methods for measuring vitamin B12 in foods are compromised by contaminants (e.g. soil, bacteria, etc.) that contain detectable concentrations of inactive B12 analogs, which may explain the origin of this belief.[7] More recent studies reveal certain mushrooms and algae as the only naturally occurring sources of B12 outside of the animal kingdom.[8] Of these, only Chlorella has demonstrated the ability to reduce methyl malonic acid (MMA) levels (a product of B12 deficiency) in human subjects.[9]

Cultivation details: We have very little information on this species and do not know how hardy it will be in Britain, though judging by its native range it should succeed outdoors at least in the milder parts of this country. The following notes are based on the general needs of the genus. Requires a deep moist fertile soil in dappled shade or full sun[200]. Plants are reliably perennial if they are prevented from setting seed[200].
Propagation
Seed - best sown in a cold frame as soon as it is ripe since the seed only has a short viability[200]. Seed can also be sown in the spring, though germination rates will be lower. It requires light for germination[200]. When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter, planting them out into their permanent positions in the spring. The seed can also be sow in situ as soon as it is ripe.

Summary of the invention
In order to solve the above problems in the prior art, the present invention proposes a method for extracting chalcone from fresh leaves of the present day. The extraction method of the present invention does not use an organic solvent, and the chalcone pure obtained by the method is pure. The product has been proved to have a purity of over 96% and a yield of over 93%.
The technical solution of the present invention includes:
A method of extracting chalcone from fresh leaves of the future, the method comprising the steps of:
a, the appropriate amount of fresh tomorrow leaves are pulverized and homogenized to obtain a homogenate;
b. adding the complex enzyme to the above homogenate and stirring well, the weight ratio of the complex enzyme to the fresh tomorrow leaves is 0.1-5:100, the pH is controlled to 5.0-6.0, the temperature is 35-40 °C, and the hydrolysis is 40. ~60min, the filtrate was collected by filtration to obtain a filtrate;
c, adding tetrachloroaluminate (1-ethyl-3-methyl)imidazole solution to the filtrate one, extracting at room temperature for 1 to 2 h, collecting the filtrate by filtration to obtain a filtrate 2;
d. The filtrate obtained in the step c is subjected to chromatographic separation on a polyamide column, eluted with ethanol, and dried at a low pressure of 55 to 60 ° C to obtain chalcone.
As a preferred embodiment of the present invention, the complex enzyme in the above step b is composed of cellulase, glucanase and phytase, and the mass ratio of the above cellulase, glucanase and phytase is 5~. 8:2~5:1~2.
Further, in the above step c, the volume ratio of the (1-ethyl-3-methyl)imidazole tetrachloroaluminate solution to the filtrate one is 2.5 to 3.5:1.
The mass ratio of the above three components of cellulase, glucanase and phytase is 7:3:2.
In the above step a, water is added for homogenization, and the amount of water added is 3 to 5 times the volume of fresh tomorrow leaves.
In the above step d, the flow rate in the chromatographic separation is controlled at 1.5 to 2.0 mL/min.

The strong polarity of the tetrachloroaluminate (1-ethyl-3-methyl)imidazole solution is closer to the polarity of the chalcone in the leaves of the next day, and the selectivity is better, and the extract is also excluded. More impurity components can significantly increase the extraction rate of chalcone, and facilitate the subsequent separation and purification of chalcone in tomorrow's leaves; in addition, non-volatile tetrachloroaluminate (1-ethyl-3-methyl) As a new type of green extractant, imidazole solution can effectively replace the traditional volatile organic solvent, minimize the harm of volatile organic solvents, eliminate safety hazards, and achieve one-step extraction at room temperature. The energy has greatly shortened the process flow and improved the production efficiency by 2-3 times, achieving the purpose of cleaning and quickly extracting chalcone.
The use of polyamide chromatography column to separate chalcone has higher selectivity, better separation with pre-order process, higher yield, simple operation, low cost, and is more suitable for industrial production.
The pure chalcone prepared by the method of the invention has experimentally confirmed that the purity is above 96%, and the yield is above 93%.

At present, domestic research on chalcone only stops by using organic chemical synthesis method to prepare chalcone (as an intermediate of flavonoids), and the obtained product has many side reactions, which takes a long time, is cumbersome to operate, and is not easy to post-treat. At the same time, the product is low in purity and has many disadvantages such as enantiomers. However, there are few studies on food and medicine for extracting chalcone active ingredients from tomorrow leaves, and there is no relevant literature after searching.
Summary of the invention
The object of the present invention is to provide a process for extracting chalcone components from the leaves of tomorrow, which can effectively reduce the activity of chalcone enzyme by using ethanol as an extraction solvent, avoid decomposition of chalcone during extraction, and improve chalcone. The extraction rate, as well as the extraction rate of 4-hydroxyderrcin (4-hydroxydisincin, 4HD for short) and xanthoangelol (xanthohumol, abbreviated as XA) in the chalcone.
The technical solution adopted by the invention:
A method for extracting chalcone components from the leaves of tomorrow, is to select dried stems and leaves of the genus Umbelliferae, Angelica Keiskei Koidzumi, and pulverize, and use 9-11 times by weight to 40% to 60% ethanol by weight ratio. The extract is hot-dipped at 65 ° C to 75 ° C for 2 to 4 times, each time for 2 to 3 hours, and the extracts are combined, and the ethanol is recovered under reduced pressure until the alcohol-free taste is obtained to obtain a flow extract; 7 to 9 times by weight is used. The water is dissolved in the extract twice, and the water extract is combined, and then extracted with ethyl acetate for 5 to 7 times. The extract is combined, and the ethyl acetate is recovered under reduced pressure to obtain an extract, which is a crude product of chalcone. AB-8 macroporous adsorption resin column, using distilled water as eluent, resin particle size 30 mesh, flow rate of 15ml/min, separation and purification, collecting eluate, eluate and then separated by 100 mesh silica gel column Purified to obtain chalcone.
The above chalcone was eluted with a gradient of chloroform-methanol (100:1?30:1), and the target 4HD and XA were collected by HPLC, and then recrystallized twice with 50% ethanol to finally obtain 4HD and XA. Pure.
The chloroform-methanol mixture was mixed at a ratio of chloroform to methanol in a volume ratio of chloroform:methanol = 100:1 to 30:1.
The advantages of the invention are:
The reaction conditions are mild and the key process parameters are easy to control.
The use of ethanol in the extraction of chalcone can effectively extract chalcone from tomorrow's leaves. The advantage is that the chalcone enzyme in the plant decomposes the chalcone during the extraction, making it free and reducing its water solubility. Sexually, the use of ethanol can reduce the activity of the enzyme in the enzyme, so that the chalcone is extracted as completely as possible, and the extraction rate is improved.
The separation and purification were carried out on a 100-mesh silica gel column, and the gradient elution was carried out with a chloroform-methanol mixture eluent. The separation efficiency of the chalcone was good, the product purity was high, and the final product extraction rate and product purity were relatively high.
Recrystallization from 50% ethanol at low temperature (0 ° C), the product obtained is of higher purity, avoiding the transformation of the target product configuration caused by recrystallization of other organic solvents (eg, xanthohumol is prone to thermal isomerism above 50 ° C) The yellow ketone is produced to reduce the target product).

EXAMPLES
The present invention will be explained in more detail with reference to the following examples, but the present invention is not limited to these examples at all.
50 g of yellow juice collected by cutting the tomorrow's leaf stem with sterilized boiled water was used as raw material (stock solution), and it was put in a round bottom flask together with 67.1 g of 99.5% ethanol, and it was kept at room temperature for 1 hour Followed by stirring. The resulting mixture was filtered with a Nutsche filter, and the filtrate was concentrated under atmospheric pressure to obtain 47.1 g of a brown oily liquid. 21.1 g of water and 51.5 g of ß-cyclodextrin were added to and mixed with 37.4 g of the obtained oily liquid, and sufficiently stirred and mixed until the whole became a paste. The obtained paste-like mixture was spread on a stainless steel vat and dried in an air dryer (50 ° C.) to obtain 58.9 g of a pale yellow brittle solid mass. This solid was pulverized with a mixer to prepare a pale yellow fine powder (33.9 g). The content of 4-hydroxyderricin and Xanthoangelol contained in the obtained fine powder was analyzed by high performance liquid chromatography under the following conditions.
[0026]
Apparatus: Shimadzu LC-6A, Shimadzu CR7A chromatography pack Column: COSMOSIL 5C18-AR (4.6 f × 250 mm) Mobile phase: methanol-water (7: 3) Temperature: 50 ° C Flow rate: 0.9 ml / min Detection: UV 330 nm Sample volume: 2 µl.
[0027]
As a result, 4-hydroxyderricin was contained at 2.29% and Xanthoangelol was included at 4.60%.
These contents correspond to 96.2% and 89.1% of 4-Hydroxyderricin and Xanthoangelol contained in the yellow broth of the ashi leaf used as a raw material, and from this it can be seen that in the powder composition of the present invention , It was confirmed that 4 - Hydroxyderricin and Xanthoangelol in the yellow broth of the leaf tomorrow were recovered with a yield as high as about 90 to 96%.
[0028]
Comparative Example 21.1 g of water and 51.5 g of dextrin (Pain Index No. 3: manufactured by Matsutani Kagaku KK) were added to and mixed with 37.4 g of the oily liquid obtained in the same manner as in Example 1, and the mixture was sufficiently stirred and mixed at room temperature. As a result, unlike the case of Example 1 using ß-cyclodextrin, a heterogeneous mixture with low viscosity was obtained. This mixture was spread on a stainless steel vat and dried in an air dryer (50 ° C.), but it turned into a candy shaped brown solid and could not be powdered.
[0029]
According to the present invention, chalcone (4-Hydroxyderricin and Xanthoangelol) having pharmacological activities such as bactericidal action (anti-gram-positive bacterial activity), antacid action, antiulcer effect, It is possible to easily solidify and powderize the tomorrow's leave juice or solvent extract contained therein without any complicated methods such as freeze-drying or spray drying. The powder composition thus obtained is useful not only as a food, a quasi-drug, a medicine per se, but also as a raw material (bulk) used for formulation of these.

Leaf tissue culture and rapid propagation technique of tomorrow
Technical field
The invention belongs to the technical field of plant cultivation, and relates to a technique for tissue culture and rapid propagation of leaves of tomorrow.
Background technique
The use of medicine and food in tomorrow's leaves, especially in the medicinal field, is a new vegetable that is widely recognized as a development potential. China introduced the Japanese leaves from Japan more than 20 years ago. At present, only a few companies in China have just introduced seeds, and the cultivation area is very small. The raw materials are expensive in the international market and the demand is large. In the production process, the plants of tomorrow's leaves usually enter the breeding period 1-2 years after planting, and die immediately after flowering and fruiting. The flowering period of the leaves of the next day is longer, the fruit set rate is lower, the seed maturity is different at harvesting, and the fruit is double-suspended fruit, which causes the seed germination rate of the leaves of the next day to be extremely low, and it is difficult to cultivate on a large scale. Nowadays, the breeding and cultivation techniques of seedlings of tomorrow's leaves have become a bottleneck restricting the development of tomorrow's leaves and their processed products. However, there are few reports on the breeding and cultivation of tomorrow's leaves, which leads to the price of tomorrow's leaves and their products. No high.
In order to expand the industrial production scale of tomorrow's leaves, there have been some research reports on the tissue culture of tomorrow's leaves. At present, the published research results are divided into three types: First, Li Jia and other studies have found that the petiole and leaves of tomorrow's leaves are not suitable for tissue culture as explants, but the callus induction is carried out by using the bud stem segments. Differentiation and other cultures; the second is Lu Xiuli and other reports on the use of seeds of the next day to obtain sterile seedlings for differentiation and proliferation; third, Guo Zhiyou et al reported the use of petioles and leaves as explants for tissue culture.
Compared with the above three studies, this study is the same as the use of tissue culture to construct the breeding system of tomorrow's leaves, but it is very different from the three. First, compared with Li Jia and other studies, this study broke the conclusion that leaves could not be induced as explants, and the material with bud stems was significantly restricted compared with the leaves selected in this study. Compared with Lu Xiuli and other studies, the material limitation of this study is greatly reduced. Finally, compared with the results of Guo Zhiyou and others, although the results are similar, the results of this study show that MS as a basic medium works better, and Guo Zhi The friend's report believes that the N 6 basal medium is suitable for culture, so the basal medium used for the two is very different.

Ashitaba is a part of the Izu Peninsula that is wild in the Izu Peninsula, especially on the Izu Islands, it is used as an ancient meal, and it is also used as an agriculture pasture to promote lactation of milk cows and improving milk quality . In recent years, flavor and richness like Mitsuba and celery combined and vitamins D1, B2, B6, B1. , Vitamin E 1 Lutcolin e glucos'ide, Isoquercitrin. Due to the abundance of nutritional components such as Psoralen, Angelicin, Xantbotoxin germanium, etc., demand for Ashitaba is increasing. Therefore, establishment of an effective cultivation method of Ashitaba at the scale of management was keenly desired. The present invention aims at establishing cultivation method of cultivation of Ashitaba, stabilizing cultivation, enabling production according to market demand, and cultivation method of Ashitaba with abundant component content from nutritional and livestock breeding . The present inventors established a technique relating to the present invention as a result of years of research on cultivation techniques and plant physiology. That is, when cultivating Ashitaba, it is necessary to sow and cultivate Ashitaba during the planting of this tree every 5 to 6 m after examination of the forest of trees belonging to the subgenus Yoshapushi belonging to the birch genus. It is the feature of the above. In the present invention, trees belonging to the subgenus Yashagushi are effectively used as "1st", such as Yashagushi, Okayama Yabushi and Kiln Oysterbush. The purpose and results of blending trees belonging to subgenus Yershushi and Ashitaba are summarized in the following items. In other words, it is possible to cultivate full-year Ashitaba by avoiding direct sunlight by moderately concealing the cultivation surface of Shishitaba by branches and leaves of trees. Due to avoiding direct sunlight, in Ashitaba in July and August of midsummer it is possible to obtain the cultivation yields of habitual. Because it avoided direct sunlight, transpiration of moisture from the cultivation area is suppressed and it is possible to cultivate Ashitaba also in the Shimane gorge where the rainfall is not enough. Tree belonging to subgenus Yershushi is a root nodule plant that secretes compound nitrogen from the ovine nodule or the root system into the ground. As a result of secretion of compound nitrogen, the nitrogen compound is absorbed by the roots of Ashitaba, resulting in favorable results for growth. The trees belonging to the subgenus Yashapushi showed a 2 to 3 times increase in the production of carbon dioxide compared to other non-nodular plants, so that the carbonation anabolism of Ashitaba was made active and the water retention of the soil accordingly As a result, to promote the growth of Ashitaba.
The trees belonging to subgenus Yoshabushi are deciduous leaves with a high amount of fallen leaves and high nitrogen content, decomposed on the cultivation floor and reduced to the soil, increase the humus, increase the physical, chemical and microbiological conditions of the soil As a result of improvement Improve the cultivation of Ashitaba.
Ashitaba is cultivated surrounded by trees belonging to subgenus Yashapushi, this tree has the effect of protecting the growth of Ashiba as a windbreak forest, especially during the season when wind is strong, the growth of Ashitaba in the Shimane region To be promoted.
The root system and root collapse of trees belonging to subgenus Yashagushi has a large nitrogen content compared to other plants, and as a result they are reduced into soil and promote the growth of Ashitaba. Ashitaba cultivated with mixed trees belonging to subgenus Yushabushi by a total effect of 0 or more has increased crop yield per unit area and increased nutritional and domestic feeding active ingredients, namely vitamin B 1, B 2, B 6 , Luteolin-7-glucoside, I ', B12, V, E, chlorophyll, xanthophyll, folic acid, choline, pantothenic acid, biotin, niacin, carotene, inositol, calcium, iron, magnesium, potassium, so-quercitrin, Psoralen, Angelicin, Bergapten. Increased contents of Xanthotoxin, Angelic acid, Behenic acid, germanium compounds, energy, proteins, lipids, carbohydrates, etc. There are two lines of green grasses and spring grasses in Ashitaba, but the present invention can be effectively applied to any of these. As a method of raising seedlings of Aschitiba, a method of seeding in a field that is well-grounded between the forests of the subgenus Yashapushi and growing it for 4 to 5 years as it is or a method of nursing the original size and planting the plant after leaves come out Any of these methods can be effectively applied to the present invention. For fertilization to Ashitaba, organic matter such as poultry feces and slow release chemical fertilizer etc are effective. As cultivation control of Ashitaba, once seeded, it has a tropism of 3 to 4 years. The growing stocks will bloom in the second year and become major stocks, so there is a way to change this and repeat the sprout from the root again and prolong the harvest. For harvesting, shoots and soft things are cut by hand from the root, and edible. Shipment is done by aligning well with the leaf tip, cutting off the stem, weighing and packaging it. It can also be used as a green leaf or a diver, or it can be used as a powder by drying and crushing.
Next, the present invention will be described by examples.
EXAMPLES AND COMPARATIVE EXAMPLES
Three fields are used, each of which is hereinafter referred to as 1.2. 3, field. As the first field used palm oil shavings and forests of Pleurotus albopictus, we used a slope south facing southerly with 3 to 5 'm intervals irregularly planted with Pear and Oysters. The remaining weeds and the other mushrooms were plowed and then partly plowed, and there were transplanted the seedlings of Ashitaba (5 to 6 pieces of trees) and planted them in the B 0 sub interval. When the strain grew with growth and the lower leaves got densely, the lower leaves were discarded and the ventilation was kept well. No fertilizer was used and pesticides were not used at all Q The 2nd field was a field used as a taro field, mixed with a freshwater fish and a cabbage shark, and used a field planted as a windbreak forest around the larvae did. The size of the field was 6 tn × 22 tn, and there were windproof forests in the circumference. Planting and cultivation of seedlings of Ashitaba conformed to the conditions of the field - field. In the 3 rd field, we used a large well-grounded field. The size of the field was 18 m × 43 m. Trees were totally around the surroundings. Characteristic values on cultivation in each field are shown in the following Table 1. Table 1 * (1) Exposure coefficients of the ground surface were calculated as follows. That is, the solar illuminance (Lux) of the ground surface in each field was measured. Then, the solar illuminance of the third field without shading was taken as 100, and the converted value was taken as the exposure coefficient. * (2) Wind speed coefficient of the ground surface was calculated as follows. That is, the wind speed (Th / sec) of the ground surface in each field was measured with a Robinson anemometer. Next, the wind speed of the third field without shading was taken as 100, and the converted value was taken as the wind speed coefficient. Next, the results of cultivation of Ashitaba in the first to third field are as shown in Table 2. Table 2 * (3) Yield factor of the field was calculated as follows. In other words, the yield of adults of each plot was measured in increments of 9 for 10 ares. Then, the yield factor of the third field was converted to 100, and the result was taken as the yield coefficient. As shown by the above results, it was observed that the yield of the Erythrabania increased by the method of the present invention. The third field is an example of comparison.
