均匀设计考察壳聚精澄清法精制降糖通脉水提液

Study on Chitosan Clarification Refining the Decoction of Jiangtangtongmai by Homogenous Design Method

目的:利用均匀设计法探讨壳聚糖澄清剂用于精制降糖通脉水提液时对梓醇含量的影响。方法:用高效液相色谱法对壳聚糖澄清法及乙醇醇沉后的药液所含的梓醇含量进行测定。结果:壳聚糖澄清法可较好地保存降糖通脉君药地黄中有效成分梓醇的含量。结论:壳聚糖澄清法可替代醇沉用于精制降糖通脉水提液。

Objective: To study the effect of chitosan clarification refining the decoction of Jiangtangtongmai by homogenous design method.Methods:The content of catalpol in the refined decoction by the alcohol-precipitation method and chitosan clarification method was determined by RP-HPLC. Results: Catalpol can be well preserved by chitosan clarification method. Conclusion: Chitosan clarification method can replace alcohol-precipitation method in refining of the decoction of Jiangtangtongmai.
