摘要
目的 :探讨壳聚糖絮凝法代替乙醇沉淀法用于脑清口服液 (葛根 ,黄芪等 )制备的可行性。方法 :考察两种澄清法的沉淀效果、过滤难易、对主要有效成分含量影响并对稳定性进行了比较。结果 :壳聚糖絮凝法与醇沉法同样能使药液澄清 ,前者能更有效地保留药液中的有效成分 ,又能保证制剂的稳定性 ,缩短生产周期 ,降低成本。结论
Objective: To study clarifying for Naoqing Oral Liquid (Radix Puerariae, Radix Astragali, etc.) with chitin instead of ethanol. Methods: By studying precipitation effect of two clarification methods, in the meantime, studying the influence of different concentration of chitin on the clarification effect of Naoqing Oral Liquid. Results: Chitin had the more effective components than ethanol, and assured the stability of the preparation and shortened production period of the preparation. Conclusion: Chitin can clarify Naoqing Oral Liquid instead of ethanol.
