【摘要】 在抗癌活性筛选结果指导下 ,对近无柄金丝桃 (HypericumsubsessileN Robson)有活性的部位同步进行了化学成分的分离纯化。首次从该植物中得到 6个黄酮类化合物 ,经理化性质和波谱分析 ,分别鉴定为槲皮素 (quercetin ,1)、槲皮甙 (quercitrin ,2 )、异槲皮甙 (isoquercitrin ,3)、芦丁 (rutin ,4)、山柰酚(kaempferol,5 )、Ⅰ 3,Ⅱ 8 双芹菜甙元 (Ⅰ 3,Ⅱ 8 biapigenin ,6 )。更多还原

【Abstract】 Cytotoxicity screening of extracts of Hypericum subsessile were carried out by L 1210 cell.Six flavonoids,quercetin(1),quercitrin(2),isoquercitrin(3),rutin(4),kaempferol(5) and Ⅰ3,Ⅱ8-Biapigenin(6),were isolated from Hypericum subsessile.Their structures were identified by means of spectroscopy.All the compounds are reported firstly in this genus.更多还原
