猪用生长激素脂质体的化学稳定性

Study on Chemical Stability of PST Liposome

通过逆相蒸发法制备猪用生长激素脂质体 ,重点探讨外界环境和主要原料对猪用生长激素脂质体化学稳定性的影响 .经过实验研究发现 ,猪用生长激素脂质体在环境液 pH为 7左右和冷藏状态下较稳定 ,包封率达到 89%左右 .

Through the experiments, it was proved that PST liposome prepared by reverse phase evaporation could be in the most stable state under neutral pH of environmental solution and refrigerated storage. Encapsulation was 89%. This is the first step of the research on applying PST liposome on clinical tests.
