摘要
目的研究药用滨海植物厚藤[Ipomea pes-caprae(Linn.)Sweet]的化学成分。方法采用硅胶柱色谱和Sephadex LH-20凝胶柱色谱从厚藤的正丁醇提取物中分离到7个化合物,经理化常数和波谱分析确定这7种化合物的结构。结果这7种化合物分别为:山柰酚(1)、槲皮素(2)、杨梅黄酮(3)、胡萝卜苷(4)、山柰苷(5)、栎皮苷(6)和槲皮素-7-O-β-D-葡萄糖苷(7)。结论其中化合物杨梅黄酮、胡萝卜苷、山柰苷、栎皮苷和槲皮素-7-O-β-D-葡萄糖苷为首次从该种植物中分离得到。
Abstract
OBJECTIVE To study the chemical constituents of Ipomoea pes-caprae(Linn.) Sweet.METHODS The compounds were isolated and purified using column chromatography with silical gel and Sephadex LH-20,and their structures were identified by their physical and spectral data.RESULTS Seven compounds were isolated and elucidated as kaempferol(1),quercetin(2),myricetin(3),daucosterol(4),kaempferitrin(5),guercetrin(6) and guercetrin-7-O-β-D-glucoside(7).CONCLUSION Myricetin,daucosterol,kaempferitrin,guercetrin and guercetrin-7-O-β-D-glucoside were firstly isolated from this species.
