壳聚糖用于金银花等絮凝澄清研究

Study on Clarification Process of Floslonicerae Japonicae and Fructus Gardeniae by Chitosan

目的研究壳聚糖絮凝技术用于金银花．栀子药材的中药水提液精制的可行性。方法考察两种澄清法的沉淀效果对主要有效成分含量影响，并对其稳定性进行了比较。结果壳聚糖絮凝法与醇沉法同样能使药液澄清，前者保留药液中的有效成分比醇沉法多，壳聚糖絮凝法缩短生产周期，降低成本。结论壳聚糖絮凝法可代替乙醇沉淀法用于金银花、栀子药材的中药水提液的澄清。

Objective Research into the feasibility of refining floslonicerae japonicae and fructus gardeniae by chitosan sedimentation process. Methods To find out the affection of effective components and the comparison of stability in the two processes. Results Both the processes by chitosan and by ethanol have clearing action, the former reserved more effective components than the latter. The chitosan sedimentation process can also shorten manufacture periods and reduce cost. Conclusion The process by chitosan can substitute for process by ethanol sediment in production of floslonicerae japonicae and fructus gardeniae.
