摘要
[目的]建立护肝宁胶囊中大黄素RP—HPLC的含量测定方法。[方法]采用Kromasil—C18柱(5μm,4.6mm×250mm);流动相为甲醇-0.1%磷酸溶液(85:15);检测波长为289nm。[结果]大黄素的进样量在0.1019~1.019μg范围内线性良好,r=0.9999;平均回收率为97.13%,RSD=1.36%(n=6)。[结论]本法操作简便易行、灵敏度高、重现性好、准确可靠,可用于护肝宁胶囊的质量控制。
[ Objective] To establish a special determination of Emodin in huganning capsules by RP- HLPC. [ Methods] Kromasil- C18 column (5μm,4.6mm×250mm)was choasen, The methanol- 0.1% phosphoric acid (gradient)was used as the mobile phase, and the detection wavelength was at 289nm. [Results] For emodin ,the linear range was 0. 1019 - 1. 019μg and the average recovery was 97.08% with corresponding RSD= 1.37% ( n = 6). [Conclusion]The method is simple, sensitive, reproducible, accurate and can be used for the quality control of Chinese medicine Huganning capsules.
