Abstract

From the berries of Rhamnus petiolaris a new acylated flavonol glycoside was isolated and identified as rhamnetin 3-O-[3""-O-(p-coumaroyl)-alpha-L-rhamnopyranosyl(1-->3)- alpha-L-rhamnopyranosyl(1-->6)]-beta-D-galactopyranoside. Additionally, five known flavonol glycosides, rhamnetin, rhamnazin, quercetin and kaempferol 3-rhamninosides, and quercetin 3-rhamnoside were isolated.

摘要

从鼠李属植物叶柄鼠李的浆果中分离得到一种新的酰化黄酮醇苷，鉴定为鼠李素3 - O - [3″ - O -（对香豆酰基）-α - L - 鼠李吡喃糖基（1→3）-α - L - 鼠李吡喃糖基（1→6）]-β - D - 吡喃半乳糖苷。此外，还分离得到了5种已知的黄酮醇苷，即鼠李素、鼠李嗪、槲皮素和山奈酚3 - 鼠李糖苷，以及槲皮素3 - 鼠李糖苷。
