Structure Identification:

Zhong Yao Cai. 2012 Jul;35(7):1088-90.

Chemical constituents of ethyl acetate extract from Polygonum perfoliatum.[Pubmed: 23252271]

METHODS AND RESULTS:
The chemical constituents of Polygonum perfoliatum were isolated and purified by chromatography on silica gel, Sephadex LH-20 and Semi-preparative HPLC. The structures of compounds were elucidated and identified by physicochemical properties, H-NMR, 13C-NMR and ESI-MS. Ten compounds were isolated and identified as 5-hydroxymethyl-2-furaldEhyde (1), methyl caffeoate (2), protocatechuic aldehyde (3), quercetin (4), pinocernbrin (5), catechin (6), taxifolin (7), Taxifolin 3-O-beta-D-xylopyranoside (8), 13-epitorulosal (9), coumarin-7-O-beta-D-glucose glycosidic (10).
CONCLUSIONS:
Compounds 6-9 are isolated from this plant for the first time.
