摘要
目的:研究藏药白花铃子香(Chelonopsisalbiflora)地上部分的化学成分。方法:利用多种色谱手段进行分离纯化,根据化合物理化性质和波谱分析鉴定化合物的结构。结果:从藏药白花铃子香的氯仿部分分离得到7个化合物,分别鉴定为:1β一羟基羽扇豆醇(1)、羽扇豆醇(2)、β一谷甾醇(3)、β一羟基半日花-8(17),14-二烯-19-醛(4)、19.乙酰氧基.13.羟基半日花.8(17),14.二烯(5)、对甲基反式肉桂酸(6)、香草酸(7)。结论:化合物1~7均为首次从该属植物中分离得到。
Objective : To study the chemical constituents of Chelonopsis albiflora. Methods : The compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis( El-MS, I H- NMR, 13 C-NMR. Results : Seven compounds were isolated and identified as lji-hydroxylupenol ( 1 ), lupenol ( 2 ) ,13-sitosterol ( 3 ), 13- epi-torulosal( 4 ), 19-acetoxy-13-hydroxylabada-8 ( 17 ), 14-diene ( 5 ), ( E )-p-methyl cinnamic acid ( 6 ) and vanillic acid ( 7 ).Conclusion:All compounds are isolated for the first time from this genus.
