云南长序荆化学成分研究

Studies on the Chemical Constituents from Vitex peduncularis Wall in Yunnan Province

为研究长序荆的化学成分,利用各种色谱技术从长序荆中得到11个化合物,其结构用波谱分析方法分别鉴定为：3’,5-dihydroxy-3,4’,7-trimethoxyflavone（1）,3’,5-dihydroxy-4’,6,7-trimethoxyflavone（2）,4’,5,7-trihydroxyflavanone（3）,kaempferol（4）,luteolin（5）,kaempferol-3-O-β-D-glucoside（6）,vitexin（7）,isovitexin（8）,daucosterol（9）,β-谷甾醇（10）,豆甾醇（11）。其中,化合物1-6为首次从该植物中分离得到。

In order to study the chemical constituents of Vitex peduncularis Wall, eleven compounds were isolated from 95% EtOH extract of the plant by various chromatography methods. The structures of them were identified by spectroscopic analysis to be ： 3＇ , 5 - dihydroxy - 3,4＇ , 7 - trimethoxy fla- vone （1）, 3＇ , 5 -dihydroxy - 4＇ , 6, 7 -trimethoxy flavone （2）, 4＇ , 5, 7 -trihydroxy flavanone （ 3 ）, kaempferol （4）, luteolin （5）, kaempferol - 3 - 0 -/3 - D - glucoside （6）, vitexin （7）, isovitexin （8）, daucosterol （9）,β - sitosterol （10） , stigmasterol （ 11 ） , respectively. Among them, compounds 1 -6 were obtained from this plant for the first time.
