摘 要:研究藏药多刺绿绒蒿的化学成分。利用硅胶、Sephadex LH-20、ODS等色谱技术进行分离纯化,通过1H,13C-NMR等理化数据及与文献相对照进行结构鉴定,采用MTT法对部分化合物进行体外细胞毒活性评价。从多刺绿绒蒿的乙醇提取物中分离得到9个化合物,分别鉴定为马齿苋酰胺E(1),N-反式对羟基肉桂酰基-对羟基苯乙胺(2),金圣草黄素(3),芹菜素(4),大风子素(5),对羟基肉桂酸葡萄糖酯(6),stigmast-5-ene-3β-ylformate(7),3β-hydroxy-7α-ethoxy-24β-ethylcholest-5-ene(8),β-谷甾醇(9)。化合物6~8 为首次从该属中分离获得,1,3为首次从该种植物中分离得到。化合物1对人肝癌细胞系HepG2具有显著的细胞毒活性。A phytochemical investigation on the aerial parts of a Tibetan medicine Meconopsis horridula,by solvent extraction,repeated chromatographies on silica gel,Sephadex LH-20,and preparative TLC techniques,led to the isolation of 9 compounds. By spectroscopic analysis and comparison of its 1H and 13C-NMR data with those in literatures,their structures were identified as oleracein E(1),N-(trans-p-coumaroyl)tyramine(2),chrysoeriol(3),apigenin(4),hydnocarpin(5),p-coumaric acid glucosyl ester(6),stigmast-5-ene-3β-ylformate(7),3β-hydroxy-7α-ethoxy-24β-ethylcholest-5-ene(8),and β-sitosterol(9),respectively,among which compounds 6-8 were isolated from the genus for the first time,and 1,3 were isolated from the species for the first time. A MTT method was applied to evaluate the cytotoxic activity of compounds 1-4 against the human hepatocellular liver carcinoma cell line(HepG2),and compound 1 showed significant cytotoxicity against HepG2,with its inhibitory rate of 52.2% at 10 μmol·L-1.
