Abstract

The roots of Dipsacus asper have yielded two new triterpenoid saponins, dipsacus saponins B [1] and C [2], which have been characterized by chemical and spectral means and spectral means as hederagenin-3-O-beta-D-glucopyranosyl-(1-->4)-[alpha-L-rhamnopy ran osyl- (1-->6)]-beta-D-glucopyranosyl-(1-->3)-alpha-L-rhamnopyranosyl-(1-->2)-a lpha- L-arabinopyranoside [1] and hederagenin-3-O-beta-D-xylopyranosyl-(1-->4)- beta-D-glucopyranosyl-(1-->4)-beta-D-glucopyranosyl-(1-->3)-[alpha-L- rhamnopyranosyl-(1-->4)]-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L- arabinopyranoside [2].

摘要

糙叶续断的根中产生了两种新的三萜皂苷，续断皂苷B [1]和续断皂苷C [2]，它们已通过化学和光谱方法进行了表征，光谱方法表明其为常春藤皂苷元-3-O-β-D-吡喃葡萄糖基-(1→4)-[α-L-鼠李吡喃糖基-(1→6)]-β-D-吡喃葡萄糖基-(1→3)-α-L-鼠李吡喃糖基-(1→2)-α-L-阿拉伯吡喃糖苷 [1] 和常春藤皂苷元-3-O-β-D-吡喃木糖基-(1→4)-β-D-吡喃葡萄糖基-(1→4)-β-D-吡喃葡萄糖基-(1→3)-[α-L-鼠李吡喃糖基-(1→4)]-α-L-鼠李吡喃糖基-(1→2)-α-L-阿拉伯吡喃糖苷 [2]。
