杉寄生化学成分

Chemical Constituents from Macrosolen cochinchinensis

目的：研究杉寄生的化学成分。方法：采用Sephadex LH-20柱色谱、硅胶柱色谱、重结晶等方法分离和纯化。结果：从杉寄生中分离得到10个化合物,通过波谱学方法鉴定为：羽扇豆醇（1）,环桉烯醇（2）,表木栓醇（3）,（23Z）-9,19-cycloart-23-ene-3α,25-diol（4）,木栓酮（5）,正三十二烷醇（6）,β-谷甾醇（7）,三十二酸（8）,芦丁（9）,荭草苷（10）。结论：化合物1-8及化合物10为首次在该植物中分离得到。

Objective： To study the chemical constituents of Macrosolen cochinchinensis. Method： The chemical constituents were isolated and purified from M. cochinchinensis by Sephadex LH-20, silica column chromatography and recrystallization. Their structures were elucidated on the basis of their physicochemical properties and spectra analysis. Result： Ten compounds were obtained and identified as lupeol （1）, cycloeucalenol （2）, friedelan-3β-ol （3）, （23Z） -9, 19-cycloart-23-ene-3α, 25-diol （4）, friedelan-3-one （5）, dotriacontan-l-ol （6）, β-sitosterol （7）, lacceroic acid （8）, rutin （9）, orientin （10）. Conclusion ： Compounds 1-8 and 10 were isolated from this plant for the first time.
