Title:
4G-O-α-D-GLUCOPYRANOSYLRUTIN CRYSTAL AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/083554
Kind Code:
A1
Abstract:
The problem addressed by the present invention is to provide a 4G-α-glucosylrutin crystal, a 4G-α-glucosylrutin crystal-containing powder, an application of same as a drug starting material, and applications as a cosmetic product starting material and a food product starting material. The problem is solved by providing a 4G-α-glucosylrutin crystal configured from a ratio of one molecule of 4G-α-glucosylrutin, one molecule of ethanol, and 8 molecules of water.
