摘要
目的对清热祛疮合剂进行了稳定性试验研究。方法采用经典恒温法以紫外光谱法下277 nm的吸收度A值为定量指标进行稳定性试验。结果该制剂25℃的贮存期0.9为0.83年,活化能为81.91 KJ.mol-1。结论清热祛疮合剂的贮存期初步可定为1年。
Aim To study the stability of qingrequchuang mixture.Methods The classical constant-temperature experiment method was applied and the absorbance units at 277nm of UV was the quantity index to test the stability.Results It has been shown that the preparations are stable in ten months at the room temperature and the activation was 81.91KJ·mol-1.Conclusion The storage period of qingrequchuang mixture can be one year.
