Objective:
To study the chemical constituents of Polygonum perfoliatum.
Methods:
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.
Results:
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).
Conclusion:
[corrected] Compounds 6-9 are isolated from this plant for the first time.
