目的研究那藤Stauntonia obovatifoliola subsp.urophylla的化学成分。方法采用溶剂法及多种色谱技术进行化学成分的分离纯化,利用现代波谱技术进行结构鉴定。结果从那藤茎95%乙醇提取物中分离得到9个化合物,分别鉴定为软木三萜酮(1)、二十烷酸(2)、羽扇豆醇(3)、β-谷甾醇(4)、豆甾醇(5)、齐墩果酸(6)、常春藤皂苷元3-O-α-L-吡喃鼠李糖基-(1→2)-α-L-吡喃阿拉伯糖苷(7)、β-胡萝卜苷(8)、蔗糖(9)。结论所有化合物均为首次从该植物中分离得到。 Objective To study the chemical constituents of Stauntonia obovatifolia subsp. Methods Solvents and various chromatographic techniques were used to separate and purify the chemical constituents. The structures were identified by modern spectroscopic techniques. Results Nine compounds were isolated from 95% ethanol extract of cane and identified as triterpene (1), eicosanoic acid (2), lupeol (3), β-sitosterol , Stigmasterol (5), oleanolic acid (6), hederagenin 3-O-α-L-rhamnopyranosyl- (1 → 2) -α-L-arabinopyranoside ), Β-daucosterol (8), sucrose (9). Conclusion All the compounds were isolated from this plant for the first time.
