中草药制剂回收乙醇的质量分析

Quality analysis in recycled ethanol of medicinal herb preparations

目的:分析中草药制剂回收乙醇的质量情况,为净化处理提供依据。方法:采用对比法,取乙醇配制成与中草药制剂回收乙醇相近的浓度,按乙醇质量标准检验比较其质量差异。结果:中草药制剂回收乙醇的外观、酸度、易氧化物、不挥发物等项目均不符合规定。结论:中草药制剂回收乙醇被带入了某些中药成分的杂质,必须通过处理后才能再应用,以利于保障制剂质量。

Objective：To analysis the quality in the recycled ethanol of medicinal herb preparations and to provide the basis of the purification disposal. Methods： The recycled ethanol was compared with the fresh ethanol that had the same concentration as the recycled ethanol according to the quality standard of ethanol to find the difference between them. Results： The recycled ethanol of medicinal herb preparations did not accord with stipulations at aspect, acidity, readily oxidizable substance, non-volatile substance and etc. Conclusion： The recycled ethanol of medicinal herb preparations is brought into some impurities in the medicinal herbs. It can＇t be used because there are impurities in the recycled ethanol until it is treated eligibly.
