摘　　要：对马齿苋有保健功效的总黄酮进行研究。采用常规提取与萃取法,柱层析方法分离并重结晶得单体,用化学鉴别与波谱相结合的方法确定结构。结果表明:从含总黄酮的乙酸乙酯部位分离到β-谷甾醇、芹菜素、山萘酚、木犀草素、槲皮素、尿囊素。芹菜素、山萘酚、木犀草素、槲皮素为首次从马齿苋分离得到。马齿苋有保健功效的总黄酮既有上述黄酮成分又有其它活性成分,但以黄酮成分为主。To study the Chemical constituents from Portulaca oleracea L.Compounds were isolated by silica gel column and Sephedex LH-20 and identified by physicochemical data and spectral analysis Sixes compositions were isolated and identified asβ-sitosoterol ;apigenin;kaempferol;luteolin;quercertin;allantion.Apigenin;kaempferol;luteolin,quercertin first have been isolated from Portulaca oleracea L.the total flavonoids note only have flavonoids but also non-flavonoids.but major contents flavonoids.
