壳聚糖对当归水煎液的澄清效果

Effect of chitosan on clarification of water decoction of Angelica sinensis

目的 :本文探讨了壳聚糖用于当归水煎液澄清分离时对阿魏酸提取率的影响。 方法 :在研究过程中对絮凝澄清液、醇沉液、水煎液进行相关成分的 TL C鉴别及含量测定 ,并作平行比较。结果 :壳聚糖絮凝剂对当归水煎液能起到一定的澄清作用。 结论 :壳聚糖絮凝剂能有效保留当归水煎液中大部分指标成分 ,阿魏酸的含量及转移率较醇沉法为高。

Objective:To investigate the effect of chito san on the content of ferulic acid in the process of clarifying water decoction of Angelica sinensis. Methods:Active ingredients in water decoc tion, chitosan-settled solution and alcohol-settled solution were assayed by T LC and compared with each other. Results:The results indicated that chitosan could preserve active principles while clarifying Angelica sinensis decoction. Conclusion:The transferring ratio and content of ferulic acid with chitosan-settling method are higher than those with alcohol- settling method.
