Problems solved by technology

[0003] At present, extraction and separation from plants is still the main way to obtain secondary metabolites. However, most secondary metabolites are low in plants and only accumulate in special tissue parts, specific growth stages or growth environments. Reliance on wild resources endangers endangered species and damages the environment
The cultivation of medicinal plants can alleviate these problems to a certain extent, but due to the high requirements for the growth environment, long time consumption, and heavy labor, the cultivation of medicinal plants is costly and difficult
Most secondary metabolites have complex structures and often contain specific stereochemical structures, making total chemical synthesis often impossible or economically unfeasible

Embodiment 1

[0036] (1) Wash and dry the yeast cells (baker's yeast, Huzhou Lilly Biotechnology Co., Ltd., product number: LM801H), pulverize, soak in 5% HCl solution for 5 hours under stirring, filter, and take the precipitate;

[0037] (2) Wash the precipitate from step (1) until neutral, add 8% NaOH solution, heat to 40°C, stir and keep warm for 2 hours, filter, and take the precipitate;

[0038] (3) Wash the precipitate in step (2) to neutrality, and add 1% KMnO successively 4 solution and 1% NaHSO 4 solution, rinsed separately, washed and dried to obtain a solid extract;

[0039] (4) Add 0.5% acetic acid solution to the solid extract in step (3) according to the mass ratio of solid to liquid: 1:25, stir until completely dissolved, centrifuge (4000 rpm, 15 minutes), and take the supernatant;

[0040] (5) The supernatant of step (4) was neutralized to pH 8.5 with 5% NaOH solution, allowed to stand for 8 hours, centrifuged (3000 rpm, 15 minutes), and the precipitate was taken, dehydrated...

Embodiment 2

[0043] In Tudian Town, Tongxiang City, Zhejiang Province, the main cultivar of Chrysanthemum chrysanthemum was tested in field cultivation, with a width of 1.5m, 2 plants per hole, 5000 plants / mu, and a hole distance of 15-15cm. Planting on April 15, first layering on May 16, second layering on July 15, topping twice on June 10 and July 11. Carry out conventional fertilization, weeding and pest control according to the cultivation and management requirements of Chrysanthemum chrysanthemum.

[0044] Experimental treatment 1: the optimum application period of yeast extract. Set to 4 different periods: (1) Seedling stage (May 5th); (2) Branching stage (July 20th); (3) Before budding stage (September 10th); (4) The budding period (September 20).

[0045] Treatment method: the area of ​​each treatment plot is 15m 2 , and each treatment was repeated 3 times. Prepare 0.4g / L yeast extract (YS) solution according to 300ml / m 2 Spray evenly on the leaves of the seedlings. When 60% ...

Abstract

The invention provides a processing method capable of improving medicinal component content of Hangzhou white chrysanthemums. The method comprises the following steps: planting Hangzhou white chrysanthemums according to a normal condition; taking yeast extract to prepare a solution with the concentration of 0.1-0.5g/L about 10 days before a squaring stage of the Hangzhou white chrysanthemums; spraying the obtained solution to blades of the Hangzhou white chrysanthemums in an even mode according to the dosage of 200-400 ml/m <2>; harvesting the Hangzhou white chrysanthemums when the buds open by 50-70%, carrying out deactivation of enzymes and drying, and obtaining Hangzhou white chrysanthemums finished products. The processing method capable of improving the medicinal component content of the Hangzhou white chrysanthemums has the advantages that the medicinal component content of the Hangzhou white chrysanthemums can be remarkably improved by utilization of the method.

Description

(1) Technical field [0001] The invention relates to a treatment method for increasing the content of medicinal components of Chrysanthemum chrysanthemum. (2) Background technology [0002] The traditional Chinese medicinal material industry, which is dominated by medicinal plants, is one of the few advantageous industries with independent intellectual property rights in my country, and it is also one of the key industries supported by the country during the 12th Five-Year Plan and one of the ten leading agricultural industries in Zhejiang Province during the 12th Five-Year Plan. Medicinal plants can not only be used as raw materials for chemicals, but also used as medicines in traditional medical care and treatment. In medicinal plants, the content of medicinal ingredients is the material basis for determining medicinal plants. [0003] At present, extraction and separation from plants is still the main way to obtain secondary metabolites. However, most secondary metabolite...
