Objective: Establish the two methods for the determination of entrapment efficiency of liposomes. Method: Sephadex G-50 and cation exchange resin were used to separate free vincristine sulfate from liposomes. The concentration of vincristine sulfate was determined by HPLC. The result was analyzed with SPSS. Result: The entrapment efficiency of the different drug loading liposome determined by the two methods was consistent. Conclusion: Both methods can be used to determine the entrapment efficiency of vincristine sulfate liposomes.
