维药多伞阿魏的化学成分研究

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12.87 μmol/L.
