| Abstract:Objective To develop a RP-HPLC method for determination of baicalin in Zhenhuang Wan.Methods Alltima C18 column was used and methanol-water-acetic acid glacial (50 : 50 :1) was used as mobile phase,detection wavelegth was 273nm.Results There was a good linear relationship between the concentration of baicalin and absorption area value in range of 7.444 - 37.220μg r = 0.999 7.The average recovery was 98.55% with RSD=0.65% (n=5).Conclusion The method was repeatable and accurate. |
