骨痹灵胶囊质量标准研究

Quality standard for Gubiling Capsules

目的:建立骨痹灵胶囊(狗鞭、三七、牛膝、淫羊藿、木香等)的质量标准.方法:采用TLC对处方中的牛膝、淫羊藿和木香进行鉴别,用HPLC测定三七中人参皂苷Rg1的含量.结果:在TLC色谱中均能检出牛膝、淫羊藿和木香;人参皂苷Rg1在1.2～6.0μg范围内线性关系良好(r=1.0000),平均回收率为96.9%;RSD为0.4%.结论:所建鉴别方法专属性强,定量方法简便、准确.可用于骨痹灵胶囊的质量标准控制.

AIM: To establish the quality standard for Gubiling Capsules (Penis Et Testis Canis, Radix Noto ginseng, Radix Achyranthis Bidentatae, Herba Epimedii, Radix Aucklandiae, etc.). METHODS: Radix Achyranthis Bidentatae, Herba Epimedii, Radix Aucklandiae were identified by TLC, and the ginsenoside Rg 1 content was determined by HPLC. RESULTS: Ginsenoside Rg 1 showed a good linear relationship in the range of 1.2-6.0 μg ( r = 1.00 0 ) and average recovery was 96.9%. RSD was 0.4%. CONCLUSION: These methods are simple, accurate and specific and can be used for the quality control for Gubiling Capsules.
