METHOD FOR IMPROVING CONTENT OF MALONYL-GINSENOSIDE IN PRODUCT
Document Type and Number:
WIPO Patent Application WO/2020/056735
Kind Code:
A1
Abstract:
A method for improving content of malonyl-ginsenoside in a product, a product containing the malonyl-ginsenoside prepared by the method, and a kit implementing the method. The method comprises the following steps: (1) mixing a sample containing the malonyl-ginsenoside and C7-10 phenyl alkyl alcohol, maintaining a temperature of a mixing system to be 95°C-150°C s and maintaining water content of the mixing system to be less than or equal to 50 ppm to obtain a first mixture containing malonyl-ginsenoside C7-10 phenylalkyl ester; (2) performing extraction on the first mixture obtained by step (1) to obtain an extract containing malonyl-ginsenoside C7-10 phenylalkyl ester; and (3) performing hydrogenation treatment on the extract obtained by step (2) to obtain a second mixture containing the malonyl-ginsenoside.
