摘要:

从小叶三点金(Desmodium microphyllum)乙醇溶液中分离得到9个黄酮类化合物,通过波谱学方法分别鉴定为(–)-表儿茶素(1)、genistein-4'-O-β-glucoside(2)、异荭草苷(isoorientin,3)、荭草苷(orientin,4)、木犀草素(luteotin,5)、异日本獐牙菜素(isoswertiajaponin,6)、luteoayamenin(7)、木犀草素-7-O-β-D-葡萄糖苷(luteolin-7-galactoside,8)、木犀草素-7-O-鼠李糖苷(luteolin-7-rhamnoside,9)。所有化合物均为首次在该植物中分离得到。

Nine flavonoids were isolated from the whole plant of Desmodium microphyllum, and identified as (–)-epicatechin (1), genistein-4'-O-β-glucoside (2), isoorientin (3), orientin (4), luteotin (5), isoswertiajaponin (6), luteoayamenin (7), luteolin-7-galactoside (8), and luteolin-7-rhamnoside (9). These compounds were isolated from Desmodium microphyllum for the first time.
