| 摘要: |
| 为深入了解麻疯树种子的化学成分,有必要对其具有生物活性的二萜类成分进行研究。该研究利用正相硅胶、ODS、制备液相等色谱分离方法,从麻疯树种子的乙醇提取物中共分离得到了6个二萜类化合物,并采用荧光偏振技术对化合物进行蛋白激酶C(PKC)抑制活性的测定。结果表明:根据化合物的理化性质、MS和NMR,并参考相关文献,这6个二萜类化合物分别鉴定为3β-acetoxy-12-methoxy-13-methyl-podocarpa-8,11,13-trien-7-one(1)、4-epi-dehydroabietic acid(2)、3β-hydroxy-19-O-acetyl-pimara-8(9),15-dien-7-one(3)、Jatrophodione A(4)、14-O-acetyl-5,6-epoxy-(14E)-jatrogrossidentadion(5)、2-Hydroxy jatrophone(6)。其中,化合物2、3、6均为首次从该植物中分离得到,且化合物2对PKCβ具有一定的抑制作用。 |

| Abstract: |
| In order to learn more about the chemical composition of Jatropha curcas seeds, the diterpenes from J. curcas seeds and their protein kinase C(PKC)inhibition activities was necessary to study. The compounds were isolated by silica gel, ODS and preparation HPLC. Six diterpenes were isolated from ethanol extraction of J. curcas seeds. The structures were identified as 3β-acetoxy-12-methoxy-13-methyl-podocarpa-8,11,13-trien-7-one(1), 4-epi-dehydroabietic acid(2), 3β-hydroxy-19-O-acetyl-pimara-8(9),15-dien-7-one(3), Jatrophodione A(4), 14-O-acetyl-5,6-epoxy-(14E)-jatrogrossidentadion(5), 2-Hydroxy jatrophone(6)by physicochemical properties, MS, NMR and some reported data. Compounds 2, 3 and 6 were isolated from J. curcas for the first time, and compound 2 showed inhibitory effect on PKCβ. |
