Abstract

Two new triterpenoid saponins, named hupehensis saponin F and G, were isolated from the water soluble part of Anemone hupehensis Lemoine. By chemical and spectroscopic evidence, their structures were elucidated as 3-O-beta-D-ribopyranosyl(1-->3)-alpha-L-rhamnopyranosyl(1--> 2)-alpha-L-arabinopyranosyl hederagennin-28-O-alpha-rhamnopyranosyl(1--> 4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl(1--> 3)-alpha-L-rhamnopyranosyl(1-->4)-beta-glucopyranosyl(1--> 6)-beta-D-glucopyranoside and 3-O-beta-D-ribopyranosyl(1-->3)-alpha-L-rhamnopyranosyl(1--> 2)-alpha-L-arabinopyranosyl hederagenin-28-O-beta-glucopyranosyl(1-->3)-alpha-rhamnopyranosyl( 1--> 4)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl(1--> 3)-alpha-L-rhamnopyranosyl(1-->4)-beta-D-glucopyranosyl(1--> 6)-beta-D-glucopyranoside, respectively.

摘要

从打破碗花花（Anemone hupehensis Lemoine）的水溶性部分分离得到了两种新的三萜皂苷，分别命名为湖北皂苷F和G。通过化学和光谱学证据，确定它们的结构分别为3-O-β-D-吡喃核糖基（1→3）-α-L-吡喃鼠李糖基（1→2）-α-L-吡喃阿拉伯糖基常春藤皂苷元-28-O-α-吡喃鼠李糖基（1→4）-β-D-吡喃葡萄糖基（1→6）-β-D-吡喃葡萄糖基（1→3）-α-L-吡喃鼠李糖基（1→4）-β-D-吡喃葡萄糖基（1→6）-β-D-吡喃葡萄糖苷和3-O-β-D-吡喃核糖基（1→3）-α-L-吡喃鼠李糖基（1→2）-α-L-吡喃阿拉伯糖基常春藤皂苷元-28-O-β-吡喃葡萄糖基（1→3）-α-吡喃鼠李糖基（1→4）-β-D-吡喃葡萄糖基（1→6）-β-D-吡喃葡萄糖基（1→3）-α-L-吡喃鼠李糖基（1→4）-β-D-吡喃葡萄糖基（1→6）-β-D-吡喃葡萄糖苷。
