目的对我国广西的萝藦科武靴藤属植物武靴藤Gymnema sylvestre 叶进行化学成分研究.方法采用硅胶柱色谱、低压柱色谱和反相中压柱色谱等方法进行化学成分的分离纯化,依据理化性质和波谱数据进行结构鉴定.结果共分离得到9 个化合物,其中4 个皂苷前文已发表.其余5 个化合物经波谱解析和理化常数测定为3 个皂苷和2 个皂苷元,分别是12- 异丁烯基-3-O-β-D- 吡喃葡萄糖(1 → 6)-β-D- 吡喃葡萄糖-28-O-β-D- 吡喃葡萄糖- 齐墩果酸酯[12-isobutylene-3-O-β-D-glucopyranosyl(1 → 6)-β-D-glucopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl ester,1],12- 异丁烯基-3-O-β-D- 吡喃葡萄糖(1 → 6)-β-D- 吡喃葡萄糖-28-O-β-D-吡喃葡萄糖(1 → 6)-β-D- 吡喃葡萄糖- 齐墩果酸酯[12-isobutylene-3-O-β-D-glucopyranosyl(1 → 6)-β-Dglucopyranosyloleanolic acid 28-O-β-D-glucopyranosyl(1 → 6) -β-D-glucopyranosyl ester,2],12- 异丁烯基-3-O-β-D- 吡喃葡萄糖(1 → 6)-β-D- 吡喃葡萄糖(1 → 6)吡喃木糖-28-O-β-D- 吡喃葡萄糖- 齐墩果酸酯[12-isobutylene-3-O-β-D-glucopyranosyl(1 → 6)-β-D-glucopyranosyl(1 → 6)-β-D-xylopyranosyl oleanolicacid 28-O-β-D- glucopyranosyl ester,3],齐墩果酸(oleanolic acid,4)和长刺皂苷元(longispinogenin,5).结论化合物均为首次从原植物中分离得到.
