Abstract
Objective Magnolol and Honokiol were identified in baojiwan pills.Methods To detemine the contents of Magnolol in baoji pills by HPLC,Hypersil ODS column was used,and methanol water(78∶22)as a mobilephase,the detection wave length was at 294nm.To detemine the contents of Honokiol in baoji pills by HPLC,Hypersil ODS column was used,and methanol water(78∶22)as a mobilephase,the detection wave length was at 294nm.Results Magnolol showed a good linear relationship at a range of 0.266mg-1.33mg(r=0.9999),The average recovery was 97.96%and RSD was1.80%.Honokiol showed a good linear relationship at a range of 0.32mg-1.6mg(r= 0.9999),The average recovery was 95.88%and RSDwas 1.56%.Conclusion The method is accurate and reliable,and can be used to conrrol the quality of baoji pills.
