Abstract: 目的:研究HepG2细胞对黄连生物碱的吸收及黄连生物碱对线粒体复合物Ⅲ表达的影响。方法:传代培养HepG2细胞,将其分为对照组、药根碱组、表小檗碱组、黄连碱组、巴马汀组、小檗碱组,设置每组药物浓度由低到高(0.25、0.50、1.00、2.00、4.00μg/mL),培养24h。通过HPLC法和Western blot法分别检测各组细胞中黄连生物碱的含量及线粒体复合物Ⅲ的含量。结果:在同一浓度下,HepG2细胞中小檗碱的浓度最高,黄连碱次之,药根碱则不能吸收;细胞中的线粒体复合物Ⅲ含量,小檗碱组最高,且小檗碱含量与线粒体复合物Ⅲ含量负相关;黄连碱组含量次之,且随着浓度变化不大;表小檗碱组、巴马汀组则影响不大。结论:小檗碱和黄连碱能提高线粒体复合物Ⅲ的表达,其他生物碱则无明显影响。
