摘　　要：目的通过制备不同配方全反式维甲酸脂质体,对处方进行优化。方法采用逆相蒸发法制备全反式维甲酸脂质体,高效液相色谱法检测活性药物含量及包封率,并进行加速试验检测其初步稳定性。结果3组全反式维甲酸脂质体包封率分别为33.98%、42.11%、70.34%,各配方稳定性好,冻干前后及0℃、25℃、40℃放置后活性药物含量无显著改变。结论全反式维甲酸脂质体制备工艺可行,质量控制方法简单、准确。Objective To prepare and optimize formulation of ATRA liposomes. Methods ATRA liposomes was prepared by reverse evaporating method and to determine the concentration and the entrapment efficiency of ATRA liposomes by HPLC. Results The entrapment efficiency of the three ATRA liposomes formulations reached 33.98%, 42.11%, 70.34% respectively. The liposome was stable. The ATRA content of three formulations almost showed no change during the observing days. Conclusion The technique of preparing the ATRA liposomes is feasible and the method of quality control is simple and accurate.
