Extraction process of resveratrol from giant knotweed

Abstract

During the extraction of resveratrol from giant knotwood, giant knotwood glycoside is hydrolyzed and enriched through organic synthesis. The extraction process includes mixing giant knotwood raw material and composite stuffing, high pressure chromatography in a high-pressure chromatographic column apparatus, gradient elution with chloroform and ethyl acetate and thin chromatographic tracking detection. The said process can reach a kilogram level yield and high product purity. The present invention may be used in extracting resveratrol and other similar product from giant knotwood material.

Description

Technical field:

[0001] The invention relates to a method for extracting resveratrol, in particular to a preparation method for extracting resveratrol from Polygonum cuspidatum. Background technique:

[0002] In the current technical scheme, resveratrol is mainly completed by the method of chemical synthesis, but because of its large investment in equipment, complicated process, high cost and low yield, it is unsatisfactory. In recent years, people have tried to extract resveratrol from the natural plant Polygonum cuspidatum and have made gratifying progress. Polygonum cuspidatum is a traditional Chinese herbal medicine in my country, which contains a large amount of polydatin (also known as resveratrol glycoside) and resveratrol, and resveratrol is a natural active substance that has a significant curative effect on human health. It has attracted widespread attention from the international community. It has been proved by scientific research and clinical application that r...
