目的:建立复方款冬花颗粒的质量标准。方法:采用TLC法对处方中的款冬花、紫菀、干姜进行鉴别;用高效液相色谱法测定没食子酸的含量。结果:在TLC色谱中检出款冬花、紫菀、干姜;没食子酸在0.336~2.016μg范围呈良好的线性关系,r=0.9999,平均回收率97.02%,RSD为1.50%。结论:本研究所建立的质量标准能够控制复方款冬花颗粒的质量。
Objective: To establish the quality standard of compound coltsfoot flowers. Methods: The T. coltsii, Tilia, and Ginger were identified by TLC, and the content of gallic acid was determined by HPLC. RESULTS: Coltsfoot flowers, Aster splendens and Ginger were detected in TLC chromatogram. Gallic acid showed a good linear relationship in the range of 0.336~2.016μg, r=0.9999. The average recovery was 97.02% and RSD was 1.50%. Conclusion: The quality standards established in this study can control the quality of the compound Coltsfoot flowers.
