  • Title: A new stilbene glucoside gallate from the roots of Polygonum multiflorum.
    Author: Kim HK, Choi YH, Choi JS, Choi SU, Kim YS, Lee KR, Kim YK, Ryu SY.
    Journal: Arch Pharm Res; 2008 Oct; 31(10):1225-9. PubMed ID: 18958411.
    Abstract:
    A new stilbenoid (1) was isolated from the root extract of Polygonum multiflorum together with eight known constituents (2-9). The chemical structure of 1 was established as the 6''-O-monogalloyl ester of (E)-2,3,4',5-beta-tetrahydroxystilbene-2-beta-D-glucopyranoside based on physicochemical and spectroscopic analyses, particularly by NMR spectroscopic data, i.e., COSY, HMQC and HMBC. Compound 1 weakly inhibited acetylcholinesterase in vitro.
