补肾活血煎的絮凝工艺研究

Flocculation procedure on Bushenhuoxue Decoction

目的 探讨壳聚糖絮凝法代替醇沉法用于补肾活血煎澄清工艺的可行性。方法 壳聚糖用于补肾活血煎的澄清 ,通过对总固形物、淫羊藿苷含量的测定 ,对壳聚糖的用量、药液浓缩比进行了优选 ,并与醇沉工艺进行了比较。结果 壳聚糖絮凝法与醇沉法同样能使药液澄清 ,在有效成分的保留上 ,前者优于后者。结论 壳聚糖絮凝法能代替醇沉法用于补肾活血煎的澄清工艺。

Object To study the feasibility of flocculation procedure on Bushenhuoxue Decoction, using chitosan instead of alcohol. Methods Using chitosan clarifier to the flocculation procedure of Bushenhuoxue Decoction; selecting the optimum content of chitosan and the density of decoction according to the total extract, and the content of icariin, comparing with the flocculation procedure by alcohol sedimentation. Results Chitosan clarifier could make the decoction clarify as alcohol does. On the retaining of active compounds, the former was better than the later. Conclusion Chitosan can be used to the flocculation procedure of Bushenhuoxue Decoction instead of alcohol.
