摘要:

为研究烟管头草(Carpesium cernuum)的化学成分及其细胞毒活性,采用多种色谱分离技术从烟管头草的95%乙醇提取物的乙酸乙酯萃取物中分离得到10个化合物。通过现代波谱技术鉴定了它们的结构,分别为(5Z)-6-[(acetyloxy)methyl]-2-oxo-2,10,14-trimethylhexadeca-5,13-diene-11α-ol(1)、(2E,10E)-1,12-dihydroxy-18-acetoxy-3,7,15-trimethylhexadeca-2,10,14-triene(2)、(2E,6Z,10E,12R)-7-[(acetyloxy)methyl]-3,11,15-trimethylhexadeca-2,6,10,14-tetraene-1,12-diol(3)、(2E,6Z,11S,12R)-3,7,11,15-tetramethylhexadeca-2,6,14-triene-7-[(acetyloxy)methyl]-1,12,19-triol(4)、plaunotol(5)、S-(+)-dehydrovomifoliol(6)、pubinernoid A(7)、豆甾醇(8)、aurantiamide acetate(9)、反式对羟基肉桂酸(10),其中化合物1为新化合物。采用MTT法对人乳腺癌细胞MDA-MB-231进行细胞毒活性,结果表明,化合物2有较强的细胞毒活性,其IC50值为6.80 μmol/L,化合物134有中等细胞毒活性。

Abstract:

To study the chemical constituents of the medicinal plant Carpesium cernuum and their cytotoxic activity,ten compounds were obtained from the ethyl acetate fraction of 95% ethanol extract of C. cernuum by ap-plying various chromatographic techniques.Their structures were elucidated and identified as(5Z)-6-[(acetyloxy)methyl]-2-oxo-2,10,14-trimethylhexadeca-5,13-diene-11α-ol(1),(2E,10E)-1,12-dihydroxy-18-acetoxy-3,7,15-trimethylhexadeca-2,10,14-triene(2),(2E,6Z,10E,12R)-7-[(acetyloxy)methyl]-3,11,15-trimethylhexadeca-2,6,10,14-tetraene-1,12-diol(3),(2E,6Z,11S,12R)-3,7,11,15-tetramethylhexadeca-2,6,14-triene-7-[(acetyloxy)methyl]-1,12,19-triol(4),plaunotol(5),S-(+)-dehydrovomifoliol(6),pubinernoid A(7),stigmasterol (8),aurantiamide acetate (9),E-p-hydroxycinnamic acid (10) respectively,based on the spectral data.Compound 1 is a new compound.The cytotoxic effect of compounds 1-4 on Human breast cancer MDA-MB-231 cell were investigated by MTT.Compound 2 exhibited strong cytotoxic activity with IC50 values of 6.80 μmol/L,and compounds 1,3 and 4 had moderate cytotoxic activity.
