Abstract:The stability of liensinine injeotion was studied by accelerating test with classical isothermal method. Results of the study showed that the decomposition of the injection was found to be a first-order reaction. The activation energy was 75030 J·mol-1. The shelf life at 10℃ and 25℃ was predicted to be about 15 months and 3 months respectively, This experiment provides a reference for the storage of the injection.
