摘要
从五风藤的地上部分95%乙醇提取物中首次分离得到12个化合物,应用波谱方法及与已知品对照的手段鉴定它们为:lup-20(29)-en-3-one(1),羽扇豆醇(2),β-谷甾醇(3),齐墩果酸(4),乌苏酸(5),β-胡萝卜苷(6),五加苷K(7),hederagenin3-O-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside(8),β-萘乙酸(9),3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]-α-L-arabinopyranosy1 oleanolic acid 28-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl ester(10),3-O-α-L-rhamnopyranosyl-(1→2)-O-β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl oleanolic acid(11),3-O-(β-D-glucopyranosiduronic acid)-oleanolic acid 28-O-β-D-glucopyranosyl ester(12).体外细胞毒活性筛选结果表明化合物7和8具有较强的细胞毒活性.
Twelve compounds were isolated from the 95% ethanol extract of the aerial part of medicinal herb Holboellia latifolia for the first time.On the basis of spectral data or comparison with authentic samples,they were characterized to be lup-20 (29)-en-3-one (1),lupeol (2),β-sitosterol (3),oleanolic acid (4),ursolic acid (5),β-daucosterol (6),Eleutheroside K (7),hederagenin3-O-α-L-rhamnopyranosyl-(1 →2)-α-L-arabinopyranoside (8) 2-(naphthalen-1-yl)acetic acid (9),3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]-α-L-arabinopyranosy1 oleanolic acid 28-O-α-L-rhamnopyranosyl-(1→4)-β-D-glucopyranosyl-(1 →6)-β-D-glucopyranosyl ester (10),3-O-α-L-rhamnopyranosyl-(1→2)-O-β-D-gluoopyranosyl-(1 →2)-α-L-arabinopyranosyl oleanolic acid (11),3-O-(β-D-gluoopyranosiduronic acid)-oleanolic acid 28-O-β-D-glucopyranosyl ester (12).Compounds 7 and 8 showed Cytotoxic activity in vitro.
