Abstract
A new chalcone glycoside, chalcone-2',4-dihydroxy-4'-O-beta-D-glucoside has been isolated from Rhamnus nipalensis together with sitosterol, lupeol, di-O-methyldaidzein, kaempferol-4'-methylether, quercetin, physcion, sitosterol glucoside, emodin and their structures established by spectroscopic data. Isolation of these compounds are the first report from this plant.
摘要
从尼泊尔鼠李中分离出一种新的查尔酮糖苷，即查尔酮-2',4-二羟基-4'-O-β-D-葡萄糖苷，同时还分离出了甾醇、羽扇豆醇、二-O-甲基大豆苷元、山柰酚-4'-甲基醚、槲皮素、大黄素甲醚、甾醇葡萄糖苷、大黄素，并通过光谱数据确定了它们的结构。这些化合物的分离是该植物的首次报道。
