摘要
天然高分子甲壳素的糖基脱去部分乙酰基所得的产物壳聚糖是一种线性高分子碳水化合物,被广泛应用于医药、化工、环保等领域。综述了壳聚糖的分布、一般性质、吸附澄清原理,及其在澄清中药提取液和制剂上的应用现状,对比了壳聚糖作为吸附澄清剂的新工艺和传统醇沉工艺,指出壳聚糖是一种安全无毒、价廉的优良吸附澄清剂,探讨了壳聚糖代替传统醇沉工艺应用于精制中药提取液和制剂的可行性和存在的问题,并提出了今后工作的建议。
As the product of natural macromolecule chitin deacetylating, Chitosan is linear macromolecule carbohydrate and is widely applied to medicine, chemical industry and environmental protection, etc.. The distribution, general properties and clarifying principle of chitosan, and the application of chitosan to the clarification of Chinese traditional medicine extraction are described . Compared with ethanol sedimentation process, the chitosan clarification is a safe, of innocuity, cheap and fine clarifying process. Chitosan clarification process can replace the conventional ethanol sedimentation process as the method of fining Chinese traditional medicine extraction and preparation. The feasibility and the problem are discussed. And the advice for future researching orientation is put forward.
