Methods The stabilities of garlic oil submicro n emulsions and injections were studied by determining the changes of dially tri sulfide(DATS) by HPLC and particle sizes by PCS after subjected to lamplight,hig h tempreture and freeze.

• 方法 采用HPLC法,以大蒜素(DATS)为指标性成分,分别对大蒜油亚微乳、大蒜油注射液进行高温高湿冷冻稀释试验以及加速试验,长期留样观察试验,并以粒径为指标观察物理稳定性。
