目的鉴别女宝胶囊中的当归和测定有效成分阿魏酸。方法采用TLC法鉴别4批女宝胶囊;用HPLC测定其中的阿魏酸,流动相为乙腈-0.085%磷酸溶液(17:83),检测波长320 nm。结果回归方程为:A=-9.02×104C+4.20×107(r=0.9988),阿魏酸的平均回收率为93.68%,RSD=1.04%(n=5)。结论所建方法简便、准确,重复性好,可用于女宝胶囊的质量控制。
Objective To identify the angelica in female Bao Capsule and determine the active ingredient ferulic acid. Methods TLC method was used to identify 4 batches of female treasure capsules. Ferulic acid was determined by HPLC. The mobile phase was acetonitrile-0.085% phosphoric acid solution (17:83). The detection wavelength was 320 nm. The regression equation was: A=-9.02×104C+4.20×107 (r=0.9988). The average recovery rate of ferulic acid was 93.68%, and RSD was 1.04% (n=5). Conclusion The established method is simple, accurate and reproducible. It can be used for the quality control of female Bao Capsule.
