| Abstract: | OBJECTIVE： To establish an HPLC method for quantitative determination of baicalin in Yanyan capsules. METHODS： The determination was performed on Kromasil C18（250 mm × 4.6 mm, 5μm） with mobile phase consisted of methanol- water-phosphoric acid（47 ： 53 ： 0.2） .The detection wavelength was set at 280 nm. RESULTS： The linear range of baicalin was 0.125-1. 216 μg（ r = 0.999 6） and its average recovery was 99.15% （RSD = 0.62%, n - 6） . CONCLUSION： The method is simple and accurate,and it can be used for the quality control of Yanyan capsule. |
