从毛茛科银莲花的根茎中分离出四种新的齐墩果烷三萜皂苷，anhuienosides C-F，以及三种已知的皂苷。茴香皂苷C-F的结构被阐明为3-O-α -L-吡喃鼠李糖基-(1 -->2)-β -D-吡喃木糖基齐墩果酸、28-O-β -D-吡喃葡萄糖基-(1 -->6) -β -D-吡喃葡萄糖酯、3-O-β -D-吡喃木糖基齐墩果酸28-O-α -L-吡喃鼠李糖基-(1 -->4)-β -D-吡喃葡萄糖基-(1 -->6) -β -D-吡喃葡萄糖酯，3-O-α -L-吡喃鼠李糖基-(1 -->2)-β -D-吡喃葡萄糖基齐墩果酸 28-O-α -L-吡喃鼠李糖基-(1 -->4)-β -D-吡喃葡萄糖基-(1 -->6)-β -D-吡喃葡萄糖酯、3-O-β -D-吡喃葡萄糖基-(1 -->3)-α -L-吡喃鼠李糖基-(1 -->2)-β -D-吡喃木糖基齐墩果酸 28-O-α -L-吡喃鼠李糖基-(1 -->4)-β分别为-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖基酯。
Four new oleanane triterpene saponins, anhuienosides C-F, together with three known saponins, were isolated from the rhizomes of Anemone anhuiensis (Ranunculaceae). The structures of anhuienosides C-F were elucidated as 3-O-alpha -L-rhamnopyranosyl-(1 -->2)-beta -D-xylopyranosyl oleanolic acid 28-O-beta -D-glucopyranosyl-(1 -->6) -beta -D-glucopyranosyl ester, 3-O-beta -D-xylopyranosyl oleanolic acid 28-O-alpha -L-rhamnopyranosyl-(1 -->4)-beta -D-glucopyranosyl-(1 -->6) -beta -D-glucopyranosyl ester, 3-O-alpha -L-rhamnopyranosyl-(1 -->2)-beta -D-glucopyranosyl oleanolic acid 28-O-alpha -L-rhamnopyranosyl-(1 -->4)-beta -D-glucopyranosyl-(1 -->6)-beta -D-glucopyanosyl ester, 3-O-beta -D-glucopyranosyl-(1 -->3)-alpha -L-rhamnopyranosyl-(1 -->2)-beta -D-xylopyranosyl oleanolic acid 28-O-alpha -L-rhamnopyranosyl-(1 -->4)-beta -D-glucopyranosyl-(1 -->6)-beta -D-glucopyranosyl ester, respectively.
