Objective To establish an HPLC method for the determination of drug encapsulation efficiency of baicalin liposomes. Methods The chromatographic column was Fortis Xi C18 column ( 250 mm × 4. 6 mm,5 μm ) ,the mobile phase was acetonitrile-0. 2%phosphoric acid solution(35 ∶65),the column temperature was 25 ℃,the flow rate was 1. 0 mL/min,the UV detection wavelength was 278 nm. Results The baicalin concentration showed a good linear relationship in the range of 6-100 μg/mL( r=0. 999 8,n=5). The average recovery rate was 99. 51%,RSD was 2. 09%( n=9 ) . Conclusion This method is accurate,simple,rapid and can be used for the determination of baicalin liposomes encapsulation efficiency.
