摘 要:目的:研究肿节风(Sarcandra glabra(Thunb.)Nakai)抗肿瘤活性部位及其化学成分。方法:用DA201大孔树脂柱分离部位,从体内动物瘤实验确定抗肿瘤活性部位;采用各种色谱方法对活性部位的化学成分进行分离,根据理化常数和波谱数据鉴定化合物结构。结果:95%乙醇洗脱部位具有显著的抗肿瘤活性,从此活性部位共分离得到13个化舍物,分别鉴定为:3,3'-双异秦皮定(3,3'-biisofraxidin,1),球松素(pinostrobin,2),异秦皮定(isofraxidin,3),棕榈酸(palmitic acid,4),白术内酯Ⅲ(atractylenolideⅢ,5),金粟兰内酯E(chloranthalactone E,6),正十五烷酸(pentadecanoic acid,7),5-羟基-7,4’-二甲氧基二氢黄酮(5-hydroxy-7,4'-dimethoxyflavanone,8),伊斯坦布林A(istanbulin A,9),2’,4'-二羟基-6’-甲氧基二氢查尔酮(uvangoletin,10),6,7-二甲氧基香豆素(scoparone,11),β-谷甾醇(β-sitosterol,12),胡萝卜苷(daucosterol,13)。结论:化合物1为新化合物,化合物5,7,11为首次从该植物中得到,化合物1—7、9—11对抑制肿瘤细胞生长有弱效。AIM: To determine the anti-tumor fraction of Sarcandra glabra (Thunb.) Nakai and separate the active constituents from this fraction. METHODS: 95% ethanol elution was determined as the anti-tumor fraction by essay in vivo. The compounds of this fraction were isolated and purified by silica column chromatography. Their structures were identified by physicochemical properties and spectral analysis. RESULTS: Thirteen compounds were isolated and identified as 3,3'-biisofraxidin(1), pinostrobin(2), isofraxidin(3), palmitic acid(4), atractylenolideⅢ (5), chloranthalactone E(6), pentadecanoic acid(7), 5-hydroxy-7,4'-dimethoxyflavanone(8), istanbulin A(9), uvangoletin(10), scoparone(11), β-sitosterol(12), daucosterol(13), respectively. CONCLUSION: Compound 1 is a new one; compounds 5, 7 and 11 have been first isolated from Sarcandra glabra (Thunb.) Nakai. Compounds 1 ~ 7 and 9 ~ 11 possess cell inhibitory activities by anti-tumor experiments.
