Title:
METHOD FOR PREPARING OXYRESVERATROL
Document Type and Number:
WIPO Patent Application WO/2024/007901
Kind Code:
A1
Abstract:
Provided is a method for preparing oxyresveratrol, comprising the steps of: (S1) providing a raw material containing mulberroside A; and (S2) using β-glucanase to perform enzymatic hydrolysis treatment on the raw material containing mulberroside A, and converting mulberroside A into oxyresveratrol so as to obtain an enzymatic hydrolysate. The method can remarkably increase the yield of oxyresveratrol, the enzymatic hydrolysis rate of mulberroside A can be as high as about 90%, and the yield of oxyresveratrol is greatly increased. The method has mild reaction conditions, simple post-treatment, and no need for special reagents, and is suitable for industrial production.
