摘要
目的 研究乌桕叶化学成分。方法 采用多种色谱方法,对乌桕叶体积分数95%乙醇提取物的石油醚、正丁醇部位成分进行分离纯化,根据波谱学数据以及理化性质鉴定化合物的结构。结果 得到12个化合物,分别为角鲨烯(1)、3β-羟基-粘霉-5-烯(2)、秦皮素(3)、无羁萜(4)、β-谷甾醇(5)、没食子酸乙酯(6)、槲皮素(7)、5-羟甲基糠醛(8)、blumenol C glucoside(9)、山柰酚3-O-β-D-葡萄糖苷(10)、1′-O-benzyl-α-L-rhamnopyranosyl-(1″-6′)-β-D- glucopyranoside(11)、莽草酸(12)。结论 化合物1~3, 8~12为从该植物中首次分离得到。
To study the chemical constituents of Sapium sebiferum leaves. METHODS The chemical constituents in the petroleum ether and n-butyl alcohol parts of the 95% ethanol extract of Sapium sebiferum leaves were isolated and purified by chromatographic methods. Their structures were elucidated by spectral data and physicochemical properties. RESULTS Twelve compounds were purified and identified as squalene(1), 3β-hydroxyglutin-5-ene(2), fraxetin(3), friedelin(4), β-sitosterol(5), gallic acid ethyl ester(6), quercetin(7), 5-hydroxymethylfurfural(8), blumenol C glucoside(9), kaempferol-3-O-β-D-glucopyranoside(10), 1′-O-benzyl-α-L-rhamnopyranosyl-(1″-6′)-β-D-glucopyranoside(11), and shikimic acid(12). CONCLUSION Compounds 1-3, and 8-12 are isolated for the first time from this plant.
