酸模叶蓼化学成分的研究
Chemical constituents from Polygonum lapathifolium
摘要
Abstract
AIM To study the chemical constituents from Polygonum lapathifolium L..METHODS The ethyl acetate fraction of 80％ ethanol extract of P.lapathifolium L.was isolated and purified by silica column,Sephadex LH-20 and ODS,then the structures of obtained compounds were identified by physicochemical properties and spectral data.RESULTS Fifteen compounds were isolated and identified as 2',4'-di-hydroxy-6'-mehtoxy-chaltone (1),2',6'-di-hydroxy-4'-methoxy-chaltone (2),2',3'-di-hydroxy-4',6'-di-methoxy-chaltone (3),kaempferol (4),quercetin (5),quercetin-3-O-α-L-rhamnoside (6),quercetin-3-O-α-L-rhamnoside (7),kaempferol-3-O-α-L-rhamnoside (8),kaempferol-3-O-β-D-glucoside (9),quercetin-3-O-β-D-galactoside (10),quercetin-3-O-β-D-glucoside (11),kaempferol-3-O-β-D-galactoside (12),quercetin-3-O-(2"-O-galloyl)-rhamnoside (13),quercetin-3-O-(2"-O-galloyl)-glucoside (14),quercetin-3-O-[(6"-O-transferuloyl)-β-D-galactoside] (15).CONCLUSION Compound 3-8 are isolated from this plant for the first time.关键词
