摘要: 为研究多根乌头(Aconitum karakolicum Rapaics)中二萜生物碱成分,本研究采用正反相硅胶柱和高效液相等色谱分离方法,从中分离得到15个二萜生物碱;通过多种波谱手段以及文献对比的方法鉴定其结构分别为aconitine(1),3-deoxyaconitine(2),16-epipyroaconine(3),neoline(4),indaconitine(5),14-benzoyl-8-O-methylaconitine(6),spicatine A(7),15-α-hydroxyneoline(8),taurenine(9),14-benzoylaconine(10),14-benzoylaconine-8-oleate(11),lappaconitine(12),beiwudine(13),13-hydroxyfranchetine(14)和8-O-linoleoyl-14-benzoylaconine(15),化合物3~15为首次从该植物中分离得到。采用MTT法和叶碟法分别考察了部分化合物的抗肿瘤和拒食活性,化合物14-benzoylaconine-8-oleate(11)对人乳腺癌MCF-7细胞、人肺癌H460细胞、肝癌HepG2细胞的IC50值分别为11.9、27.6 和 31.8 μM。乌头碱型的二萜生物碱aconitine(1)、3-deoxyaconitine(2)、 indaconitine(5)和beiwudine(13)表现出一定的拒食活性的活性(EC50 < 2 mg/cm2)。

Abstract: In order to investigate the diterpenoid alkaloid constituents of Aconitum karakolicum Rapaics,fifteen diterpenoid alkaloids were isolated by column chromatography over silica gel,RP-18,and HPLC.Their structures were identified as aconitine (1),3-deoxyaconitine (2),16-epipyroaconine (3),neoline (4),indaconitine (5),14-benzoyl-8-O-methylaconitine (6),spicatine A (7),15-α-hydroxyneoline (8),taurenine (9),14-benzoylaconine (10),14-benzoylaconine-8-oleate (11),lappaconitine (12),beiwudine (13),13-hydroxyfranchetine (14),and 8-O-linoleoyl-14-benzoylaconine (15) by extensive spectroscopic analyses and comparison of their spectroscopic data with these reported in the literature.Compounds 3-15 were isolated from the plants of A.karakolicum for the first time.In addition,the cytotoxicity and antifeedant activity of the isolates were evaluated by MTT and leaf-disk method,respectively.Compound 14-benzoylaconine-8-oleate (11) showed cytotoxicity against MCF-7,H460,and HepG2 human cancer cell lines,and the IC50 values was 11.9,27.6 and 31.8 μM,respectively.The aconitine-type diterpenoid alkaloids,aconitine (1),3-deoxyaconitine (2),indaconitine (5),and beiwudine (13) showed considerably potent antifeedant activity (EC50 < 2 mg/cm2).
