牛大力茎的化学成分研究

Chemical Constituents from the Vinestems of Millettia speciosa

从牛大力(Millettia speciosa Champ.)茎95%乙醇提取物的乙酸乙酯部分分离得到了7个化合物,经波谱分析及与文献数据对照鉴定其结构为:4,2',4'-三羟基查耳酮(1)、高丽槐素(2)、4'-羟基-7-甲氧基二氢黄酮(3)、谷甾-5-烯-3,7-二醇(4)、β-谷甾醇(5)、豆甾醇(6)和β-胡萝卜苷(7)。其中化合物3和4为首次从该植物中分离得到。

Seven compounds were isolated from the ethyl acetate extract of the vinestems of MiUettia speciosa Champ. Their structures were elucidated as ： 4,2＇, 4＇-trihydroxychalcone （ 1 ）, （-） -maackiain （2）, 4＇-hydroxy-7 -methoxy flava- none （3）,stigmast-5-ene-3,7-diol （4）,fl-sitosterol （5）,stigmasterol （6） and β-daucoster （7） using physico-chemical properties and spectroscopic data. Compounds 3 and 4 were isolated from this plant for the first time.
