Embodiment

[0014] (1) Raw material collection: Wash the collected peanut buds and store them away from light;

[0015] (2) Raw material pretreatment: Add 2-10 parts by weight of liquid nitrogen to the peanut buds to pre-freeze for 2-20 minutes, then mechanically crush to obtain leaf powder;

[0016] (3) Ultrasonic extraction of resveratrol coarse powder: put the crushed peanut buds into ethanol solvent, and use ultrasonic extraction, wherein the weight-volume (g / ml) ratio of peanut buds to ethanol solvent is 1:2-3; The extraction temperature is 55-65°C, and the extraction time is 40-80 minutes. After the extraction, the extract is filtered to obtain the filtrate and filter residue, the filtrate is concentrated and the solvent is recovered, and the recovered solvent is used to extract the filter residue again. The extraction temperature and time are the same as the first The first extraction is the same, after the extraction is finished, the extract is filtered to obtain the filtrate and ...

Abstract

The invention discloses a process for extracting resveratrol from peanut sprouts. The process includes: drying and crushing the peanut sprouts, ultrasonically extracting the resveratrol, and purifying to obtain resveratrol products. The process has the advantages that ethanol extraction is integrated with ultrasonic extraction, the ultrasonic extraction is used according to the feature that the resveratrol in the peanut sprouts is high in solubility in a weak-polarity solvent, the process is high in extraction efficiency, high in product purity and low in extraction cost and energy consumption, the solvent used in the process can be recycled, low in use amount and low in influence on environments, and the bioactivity of the resveratrol can be prevented from being destroyed during the extraction process.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a process for extracting resveratrol from peanut buds. Background technique [0002] Resveratrol is a phytoalexin naturally secreted from plants when plants are moldy or harmed by pests. It can control platelet aggregation, lower serum cholesterol, effectively prevent antioxidant and heart disease, prevent low-fat protein oxidation and normal Cells become cancer cells, prevent malignant tumor proliferation, anti-inflammation and other pathological effects. Functional foods containing resveratrol are very popular and in great demand in the market. At present, the research on the extraction and purification of resveratrol from plant resources has attracted more and more attention. In foreign countries, resveratrol is mainly extracted from grapes and grape seeds, and in China, the traditional Chinese medicine Polygonum cuspidatum is mainly used as raw materials for extract...
