摘要
Abstract
AIM To study the flavonoids from Morus nigra L.leaves.METHODS The n-butanol fraction of 80％ ethanol extract from M.nigra leaves was isolated and purified by macroporous adsorption resin and preparative HPLC column,then the structures of obtained compounds were identified by spectral data.RESULTS Eleven compounds were isolated and identified as quercetin (1),icariside Ⅱ (2),rhodionin (3),rhodiosin (4),quercetin-3-O-β-(2"-O-acetyl) galactopyranoside-7-O-α-arabia pyran glucosides (5),salidroside (6),kaempferol-3-O-β-(2"-O-α-L-rhamnopyranosyl)-glucuronide (7),quercetin-3-O-α-rhamnopyranosyl-(1 →2)-β-glucopyranosiduronide (8),rhamnetin-3-O-galactoside (9),quercetin-3'-O-β-glucoside (10),quercetin-3-O-β-D-glucopyranoside (11).CONCLUSION Compounds 1-10 are isolated from this plant for the first time.关键词
