目的:研究复方景天胶囊中主要药物的鉴别和含量测定方法。方法:采用薄层层析鉴别主要药物,用高效液相色谱法测定制剂中黄芪甲苷的含量。结果:确立了制剂中红景天和人参的鉴别方法,黄芪甲苷的线性范围为1.81~18.1μg,回归方程:Y=1.6942X+4.8026,r=0.9997。平均回收率为98.09%,RSD为1.91%。结论:该实验建立的鉴别和含量测定方法具有专属性强,重复性好,无明显干扰等特点,适用于本品质量的控制。
Objective: To study the identification and determination of the main drugs in compound Jingtian capsules. Methods: The main drugs were identified by TLC, and the contents of astragaloside IV in the preparations were determined by HPLC. RESULTS: The identification method for Rhodiola rosea and Ginseng was established. The linear range of Astragaloside IV was 1.81-18.1 μg. The regression equation was: Y=1.6942X+4.8026, r=0.9997. The average recovery rate was 98.09%, and the RSD was 1.91%. Conclusion: The identification and content determination methods established in this experiment are characterized by strong specificity, good repeatability, and no obvious interference, which are applicable to the quality control of this product.
