摘要
为明确维药多伞阿魏(Ferula ferulaeoides)的主要化学成分及其抗肿瘤活性,采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱及半制备高效液相色谱法等技术进行分离纯化,运用NMR和HRMS等波谱学方法鉴定各化合物的结构,采用计算电子圆二色谱法(ECD)判定新化合物的绝对构型.同时运用MTT法对分离得到的单体化合物在人源乳腺癌(MCF-7)细胞系上进行细胞毒活性测试.结果从多伞阿魏的乙酸乙酯萃取物中分离得到15个化合物,分别鉴定为1-(2-hydroxyl-4-methoxybenzoyl)-2S*-hydroxy-5,9,13-trimethyl-4(E),8(E),12-tetradecatrien-1-one (1),愈创木醇(2),1-(2,4-dihydroxyphenyl)-3,7,11-trimethyl-3-vinyl-6(E),10-dodecadiene-1-one (3),dshamirone (4),2,3-dihydro-7-hydroxy-2S*,3R*-dimethyl-2-[4,8-dimethyl-3(E),7-nonadienyl]-furo[3,2-c]coumarin (5), 3-(2-hydroxyl-4-methoxybenzoyl)-4S*,5R*-dimethyl-5-[4,8-dimethyl-3(E),7(E)-nonadien-1-yl]tetrahydro-2-furanone (6), fukanedone A (7), 2,3-dihydro-7-methoxy-2S*,3R*-dimethyl-2-[4-methyl-5-(4-methyl-2-furyl)-3(E)-pentenyl]-furo[3,2-c]coumarin (8),伞形花素(9),2,3-dihydro-7-methoxy-2S*,3S*-dimethyl-3-[4,8-dimethyl-3(E),7-nonadienyl]-furo[3,2-c]coumarin (10), 2,3-dihydro-7-methoxy-2S*,3R*-dimethyl-3-[4,8-dimethyl-3(E),7-nonadienyl]-furo[3,2-c]coumarin (11), 2,3-dihydro-7-hydroxy-2S*,3R*-dimethyl-3-[4,8-dimethyl-3(E),7-nonadienyl]-furo[3,2-c]coumarin (12), 2,3-dihydro-7-methoxy-2S*,3R*-dimethyl-2-[4,8-dimethyl-3(E),7-nonadienyl]-furo[3,2-c]coumarin (13),2,3-dihydro-7-methoxy-2R*,3R*-dimethyl-2-[4,8-dimethyl-3(E),7-nonadienyl]-furo[3,2-c]coumarin (14),ferulaeone C (15).其中,化合物1为新杂萜类化合物,化合物9是从该植物中首次分离得到.化合物3、4、5和15表现出潜在的抗肿瘤活性,半数抑制浓度(IC50)分别为15.11,12.98,18.01和12.87μmol/L.
