| 摘 要： | 采用柱色谱方法,从鞍叶羊蹄甲(Bauhinia brachycarpa)茎皮95%乙醇提取物的氯仿和乙酸乙酯萃取部位分离得到10个化合物。经理化性质和波谱分析确定其结构分别为:羽扇豆醇(1)、β-谷甾醇(2)、5,6,7,5’-tetramethoxy-3’,4’-methylene-dioxyflavone(3)、5,6,7,3’,4’,5’-hexanmethoxyflavone(4)、5,7,3’,4’,5’-pentame-thoxyflavone(5)、5,6,7,-trimethoxy-3’,4’-methylene-dioxyflav one(6)、胡萝卜苷(7)、没食子酸(8)、没食子酸甲酯(9)和没食子酰表儿茶素(10),所有化合物均为首次从该种植物分离得到。

| Abstract: | Ten compounds were obtained from chloroform and EtoAc fractions of 95% ethanol extract of Bauhinia brachycarpa by repeated column chromatography over silica gel and sephadex LH-20.By physical-chemical and spectral analysis,these compounds were identified as lupeol(1),β-sitosterol(2),5,6,7,5’-tetramethoxy-3’,4’-methy lene-dioxyflavone(3),5,6,7,3’,4’,5’-hexanmethoxyflavone(4),5,7,3’,4’,5’-pentamethoxyflavone(5),5,6,7-trimethoxy-3’,4’-methylene-dioxyflavone(6),daucosterol(7),gallic acid(8),methyl gallate(9),and epicatechin 3-O-gallate(10).All compounds were isolated from this plant for the first time. |
