摘 要:目的:研究胡颓子Elaeagnus pungens叶的具有抑制HeLa细胞增殖活性部位的化学成分。方法:采用硅胶柱色谱、凝胶色谱进行分离纯化,化学及波谱方法进行结构鉴定。结果:分离得到9个化合物,经理化及波谱数据分析鉴定为:对羟基苯甲酸(1),3,3’-二甲氧基槲皮素(2),咖啡酸甲酯(3),3,5-二羟基苯甲酸甲酯(4),spingic acid(5),对甲氧基苯甲酸(6),3-甲氧基山柰酚(7),山柰酚-3-O-β-D-葡萄糖苷(8),胡萝卜苷(9)。结论:化合物1-8为首次从该植物中得到。Objective: To study the chemical constituents possessing cytotoxicity activity from Elaeagnus pungens. Method: The constituents were separated through repeated chromatographic methods and their structures were elucidated by spectral analysis. Result: Five compounds were isolated from the ethyl acetate ether extract of leaves of E. pangens. Their structures were elucidated as 4-hydroxyhenzoic acid (1), 3, 3'-dimethoxyquercetin (2), caffeic acid methyl ester (3), methyl 3, 4-dihydroxyhenzoate (4), spingic acid (5), 4-methoxylhenzoic acid (6), 3-methylkaempferol (7), kaempferol-3-O-β-D-glucoside (8), dausosterol (9). Conclusion: Compounds 1-8 were isolated from this plant for the first time.
