Abstract:
AIM: To establish the quality standard of Puqinxiaoyan Tablets (Radix Scutellariae, Herba Taraxaci, Herba Corydalis Bungeanae, etc.). METHODS: TLC was used for identification of Herba Taraxaci, Herba Corydalis Bungeanae; HPLC was used for the determination of baicalin. RESULTS: The TLC identification was highly specific and the spots clear and concentrated. The linear range of baicalin was from 0.060～ 0.660?g, r = 0.99991, The recovery of the loading was 97.29%, RSD was 2.13%, respectively. The content of baicalin wasn't less than than 9.0mg per tablet. This method was easy to operate with accurate result, high sensitivity and good reproducibility. CONCLUSION: These methods are able to effectively control the quality of Puqinxiaoyan Tablets.
