Abstract:
AIM To study the chemical constituents from Polygonum posumbu.METHODS The 95％ ethanol extract from P.posumbu was isolated and purified by silica,Sephadex LH-20 and recrystallization,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Fourteen compounds were isolated and identified as n-hexacosanol (1),n-tetradecanoic acid (2),β-sitosterol (3),daucosterol (4),gallic acid (5),quercetin-3-O-(2″-O-galloyl)-β-D-glucopyranoside (6),quercetin-3-O-β-D-glucopyranoside (7),quercetin (8),o-phthalic acid bis-(2-ethyl decyl)-ester (9),inositol (10),sucrose (11),succinic acid (12),n-butyl-β-D-fructopyranoside (13),α-D-glucose (14).CONCLUSION Compounds 1,2,9,10 and 14 are isolated from genus Polygonum for the first time,compounds 1-14 are isolated from this plant for the first time
