Abstract

Two major saponins from Bellis sylvestris have been isolated and their structures determined, mainly by high-field nmr spectroscopy. One of these [2] was identical with bellissaponin BS1 from Bellis perennis, while the second is a new triterpenoid saponin [1], named besysaponin C12, and identified as 3-O-alpha-L-rhamnopyranosyl-2 beta,3 beta,16 alpha,23-tetrahydroxyolean-12-en-28-oic acid 28-O-beta-D-xylopyranosyl(1-->4)-alpha-L-rhamnopyranosyl(1-->2)-beta-D- fucopyranoside.

摘要

已从林地雏菊中分离出两种主要皂苷，并确定了它们的结构，主要采用高场核磁共振光谱法。其中一种[2]与雏菊中的雏菊皂苷BS1相同，而另一种是一种新的三萜皂苷[1]，命名为林地皂苷C12，鉴定为3 - O-α-L-鼠李吡喃糖基-2β，3β，16α，23 - 四羟基齐墩果-12 - 烯-28 - 酸28 - O-β-D-木吡喃糖基(1→4)-α-L-鼠李吡喃糖基(1→2)-β-D-岩藻吡喃糖苷。
