【摘要】 目的:研究对叶大戟Euphorbia sororia的化学成分。方法:采用硅胶、Sephadex LH-20柱分离纯化,通过理化常数和光谱数据鉴定化合物的结构。结果:从对叶大戟乙醇提取物的醋酸乙酯部位中分离得到10个化合物,经理化常数和波谱数据分析,分别鉴定为山柰酚(kaempferol,1),莨菪亭(scopoletin,2),山柰酚3-O-吡喃葡萄糖苷(kaempferol 3-O-glucopyranoside,3),槲皮素(quercetin,4),香草酸(van illic ac id,5),反式对羟基肉桂酸(E-p-hy-droxy-c innam ic ac id,6),原儿茶酸(protocatechu ic ac id,7),6,7-二羟基香豆素(6,7-d ihydroxycoum arin,8),β-谷甾醇(-βsitosterol,9),胡萝卜苷(daucosterol,10)。结论:化合物1~10均为首次从该植物中分离得到。更多还原

【Abstract】 Objective: To study the chemical constituents of the aerial parts of Euphorbia sororia.Method: Isolation and purification were carried out by silica gel and Sephadex LH-20 column chromatographies.Compounds were identified by physicochemical properties and spectral analysis.Result: Ten compounds were isolated from the plant.Their structures were identified as kaempferol(1), scopoletin(2),kaempferol 3-O-glucopyranoside(3),quercetin(4), vanillic acid(5),E-p-hydroxycinnamic acid(6),protocatechuic acid(7),6,7-dihydroxycoumarin(8), β-sitosterol(9),and daucosterol(10),respectively.Conclusion: All the above compounds were isolated from the plant for the first time.更多还原
