Title:
PREPARATION METHOD AND USE OF LENTINUS EDODES OLIGOPEPTIDE
Document Type and Number:
WIPO Patent Application WO/2022/141957
Kind Code:
A1
Abstract:
A preparation method and use of lentinus edodes oligopeptide. A lentinus edodes water extract is subjected to CTAB treatment, and then subjected to alkaline protease enzymolysis, flavourzyme enzymolysis, and activated carbon decoloration in sequence, and then a part having a molecular weight of 300-1000 Da are taken, so as to obtain the lentinus edodes oligopeptide. The oligopeptide is further prepared into a drug for treating tumors.
