摘要: 对葫蔓藤根茎总生物碱进行化学成分及肿瘤细胞毒活性研究。采用硅胶柱色谱、MCI-gel、Sephadex LH-20、HPLC等方法进行分离纯化,从葫蔓藤根茎的总生物碱中分离得到9个吲哚类生物碱,通过核磁共振、质谱等波谱分析技术将它们的结构鉴定为钩吻碱甲(1)、钩吻素子(2)、葫蔓藤碱乙(3)、钩吻氯碱(4)、19-(S)-羟基二氢钩吻氯碱(5)、钩吻碱戊(6)、19-(S)-钩吻醇碱(7)、19-(R)-钩吻醇碱(8)、钩吻素己(9)。并对分离得到的化合物通过MTT法进行抗肿瘤活性检测,发现化合物1~3对肝癌细胞HepG2显示了很好的肿瘤细胞毒活性,IC50值分别为10.02±0.16、3.98±0.11、9.87±0.18 μM。

Abstract:

To investigate the alkaloid constituents of Gelsemium elegans Benth. and evaluate their cytotoxic,the alkaloid constituents were separated and purified by chromatographic techniques,including column chromatography of silica gel,MCI-gel,Sephadex LH-20 and HPLC.Their structures were mainly elucidated by NMR and MS spectroscopic techniques.Nine indole alkaloids were isolated and purified from the roots and stems of Gelsemium elegans Benth.,they were identified as gelsemine(1),koumine(2),humantenine(3),gelsevirine(4),19-(S)-hydroxydihydrogelsevirine(5),koumidine(6),19-(S)-kouminol (7),19-(R)-kouminol(8),gelsenicine(9).The antitumor activity of the isolated compounds was detected by MTT assay.Compounds 1-3 exhibited significant cytotoxic activity against HepG2 cancer cells,with IC50 values of 10.02±0.16,3.98±0.11 and 9.87±0.18 μM respectively.
