摘要
目的:对毛泡桐叶的化学成分进行分离与鉴定。方法:利用硅胶色谱柱层析进行分离纯化,通过波谱分析鉴定其结构。结果:从毛泡桐叶的乙酸乙酯部分分离得到10个化合物,分别鉴定为:洋芹素(Ⅰ)、木樨草素(Ⅱ)、高北美圣草素(Ⅲ)、3α-羟基-乌苏酸(Ⅳ)、19α-羟基-乌苏酸(坡模酸)(Ⅴ)、2α,3α-二羟基-12烯-28-乌苏酸(Ⅵ)、乌苏酸(Ⅶ)2、α-羟基-齐墩果酸(山楂酸)(Ⅷ)、胡萝卜苷(Ⅸ)、β-谷甾醇(Ⅹ)。结论:化合物Ⅰ~Ⅹ为首次从毛泡桐叶中分离得到。
Objective:To study the chemical constituents of the leave of Paulownia tomentosa.Methods:The constituents were isolated by column chromatography and their struc-tures were elucidated through spectroscopic analysis.Results:The compounds were identified as apigenin(Ⅰ),uteolin(Ⅱ),homoeriodictyol(Ⅲ),3α-hydroxyurs-12-en-28-oic acid(Ⅳ),3β,19α-dihydroxyurs-12en-28-oic acid(pomolic acid)(Ⅴ),2α,3α-dihydroxyurs-12-en-28-oic acid(Ⅵ),ursolic acid(Ⅶ),2α,3β-dihydroxyolean-12-en-28-oic acid(maslinic acid)(Ⅷ),daucosterol(Ⅸ),β-sitosterol(Ⅹ).Conclusion:The compoundⅠ~Ⅹare obtained from the leave of Paulownia tomentosa(Thunb.)Steud for the first time.
