Abstract:
AIM To study the chemical constituents from Polygonum hydropiper L..METHODS The petroleum ether,ethyl acetate and n-butanol fractions of 95% ethanol extract from P.hydropiper were isolated and purified by silica,Sephadex LH-20 and recrystallization,then the structures of obtained compounds were identified by spectral data.RESULTS Thirteen compounds were isolated and identified as β-sitosterol (1),aniba dimer A (2),succinic acid (3),quercetin (4),gallic acid (5),daucosterol (6),quercetin-3-O-β-D-glucoside (7),kaempferol-3-O-β-D-glucoside (8),quercetin-3-O-β-galactoside (9),kaempferol-3-O-β-galactoside (10),stigmast-4-ene-3β,6a-diol (11),fumaric acid (12),ellagic acid (13).CONCLUSION Compounds 11 and 12 are isolated from genus Polygonum for the first time,compounds 2,8,10 and 13 are first obtained from this plant.
