Abstract

The invention discloses a method for increasing the content of resveratrol in peanut buds by using cell suspension culture technology, comprising the following steps: S1: preparing peanut bud culture solution: 600 μmol / L CuSO per liter 4 In the solution, add 30-35g of sucrose, 0.08-0.12g of phenylalanine, 0.3-1.5g of Botrytis cinerea fermentation extract, and 0.04-0.08g of sodium ferulate; S2: shear treatment: after sterilizing the peanut buds , cut into 0.8-1.2cm tissue pieces, added to the peanut bud culture solution, the solid-liquid ratio was controlled at 2.0g:40mL, and treated at a shear speed of 3000-7000r / min for 6-24s to obtain a peanut bud culture mixed suspension; S3: UV treatment: 25°C, put the obtained mixed suspension of peanut bud culture under ultraviolet light, and irradiate for 10-30 minutes; S4: Suspension culture: 25°C, under the condition of avoiding light and dark, put the ultraviolet light at a speed of 100-120r / min. After the treatment, the peanut buds were cultured and mixed suspension was shaken at constant temperature for 16-40 hours. The invention takes peanut buds as induction objects, combines plant cell suspension culture technology and resveratrol enrichment technology, realizes the induction of resveratrol synthesis in the process of peanut bud tissue block culture for the first time.

Description

technical field [0001] The invention belongs to the technical field of resveratrol induction and enrichment, and in particular relates to a method for increasing the content of resveratrol in peanut buds by using cell suspension culture technology. Background technique [0002] Resveratrol is a polyphenolic compound with the scientific name of 3,4,5-trihydroxystilbene, also known as stilbene, a colorless needle-like crystal, easily soluble in organic solvents such as ethanol, ether, and acetone. Resveratrol has excellent antioxidant activity. In addition, resveratrol also has good antitumor activity, and can also prevent cardiovascular disease, lower blood fat, lower blood pressure, etc. It has been widely used in food, health care, clinical medicine, cosmetics, etc. field is widely used. The main pharmacological mechanisms of resveratrol are: resveratrol can effectively remove hydroxyl radicals in the body, avoid DNA damage, and at the same time inhibit the formation of di...
