摘要 目的对没药树脂氯仿提取物的化学成分进行研究,进一步阐明没药药效物质基础。方法利用反复硅胶柱色谱、Sephadex LH-20、开放ODS柱色谱等方法进行分离纯化,根据理化性质和波谱数据等鉴定化合物的结构。MTT法评价化合物对前列腺癌细胞(PC-3)的抗肿瘤活性。结果分离得到12个化合物,分别鉴定为:proximadiol(1)、orientalol E(2)、alismol(3)、guaianediol(4)、(1(10)E,2R*,4R*,5S*)-2-甲氧基-5-乙酰基-呋喃吉玛-1(10)-烯-6-酮(5)、(1(10)E,2R*,4R*)-2-甲氧基-8,12-环氧吉玛-1(10),7,11-三烯-6-酮(6)、没药酮(7)、二氢焦莪术酮(8)、cycloartane-1α,2α,3β,25-tetrol(9)、阿尔廷-24-烯-1α,2α,3β-三醇(10)、阿尔廷-24-烯-1α,3β-二醇(11)、29-norlanost-8,24-dien-1α,2α,3β-triol(12)。结论化合物1~3为首次从没药属植物中分离得到。化合物10和12对PC-3的细胞毒活性的IC50值分别为37.4μmol·L^(-1)和26.2μmol·L^(-1)。 The chemical constituents from the CHC13 extract of Commiphora opobalsamum were isolated and purified by various kind of column chromatography on silica gel, Sephadex LH-20 and ODS, and their struc- tures were elucidated by the physico-chemical characters and the spectroscopic analysis. Twelve compounds were obtained and identified as proximadiol( 1 ), orientalol E (2), alismol ( 3 ), guaianediol ( 4 ), ( 1 ( 10 ) E, 2R * ,4R * ,5S * ) -2-methoxy-5-acetoxy-furanogermacr-1 ( 10 ) -en-6-one ( 5 ), ( 1 ( 10 ) E, 2R * , 4R* ) -2- me- thoxy-8,12-epoxygermacra-1 (10) ,7,11 -trien-6-one (6), myrrhone ( 7 ), dihydropyrocurzerenone ( 8 ), cyclo- artane- 1 α, 2α, 3β,25-tetrol ( 9 ), cycloartan-24-ene- 1 a, 2a, 3/3-triol ( 10 ), cycloartan-24-ene-1 α, 3β-diol ( 11 ), and 29-norlanost-8,24-dien-1 α, 2α, 3β-triol ( 12 ), respectively. Compounds 1 - 3 were isolated from Commi- phora for the first time. All the isolated compounds were evaluated for their cytotoxicity against the PC-3 hunman prostate tumor cell line. Only compounds 10 and 12 exhibited weak cytoxicity with IC50 values of 37.4 ixmol. L - 1,26.2 μmol·L ^- 1, respectively.
