| Abstract: | Objeetive To establish a HPLC method for determination of Baicalin in Qinhu Liyan Mixture. Methods Using OINS C18 chromatographic column 5μm （4. 6 x 250mm）, using Methanol - water - phosphoric acid （47 ： 53 ： 0.2） as mobile phase. The content was detected at a waveleng of 280nm, the flow rate was 1.0ml @ min ^-1. Results The Baicalin have a good linear relationship in the range of 0. 02638-0. 1319μg（ r = 9999）, the average recovery was 98. 38% ,RSD= 1.39% （ n = 6）. Conclusion The established method is accuracy ,sensitive and simple. It can be used for quality control of Qinhu Liyan Mixture. |
