Abstract:
Objective:To establish the quality standard for Qinzhu Liangxue mixture. Methods:Seutellaria baiealensis, glyeyrrhizae and jobstears seed were identified by TLC. Baicalin and glycyrrhizic acid were determined by HPLC. Results:Seutellaria baiealensis,glyeyrrhizae and jobstears seed could be identified by TLC. The linear range of baicalin was 0. 030- 0. 971 mg·ml -1(r = 1. 000 0),and the average recovery was 97. 74%(RSD = 2. 76% ,n = 9). The linear range of glycyrrhizic acid was 0. 013- 0. 220 mg·ml -1(r = 1. 000 0),and the average recovery was 99. 02%(RSD = 1. 79% ,n = 9)Glycyrrhizic acid. Conclusion:The method is specific,simple and accurate. It can be used for the quality control of Qinzhu Liangxue mixture.
