芪红胶囊醇提工艺的研究

Study of ethanol extraction process in qi hong capsule

目的:优选芪红胶囊醇提工艺。方法:以红景天苷提取量和干膏得率为指标,采用L9(34)正交设计试验,对提取时间、乙醇浓度、乙醇倍量因素进行考察,以确定最优提取工艺。结果:最优工艺为用14倍量95%乙醇,回流提取2次,每次1h。结论:优选得到的芪红胶囊醇提工艺稳定、可行。

Objective： To study the optimum condition for ethanol extraction process of ql nong capsule. Methods： The extraction content of salidroside and extractum yield were used as the index and orthogonal test design was used to choose the best extraction process. The effects of single parameters such as the extraction time, the concentration of ethanol, the times of ethanol were separately evaluated by synthesizing multiple guideline mthod. Results： The best extraction process was 14 times the volume of 95% ethanol, extracted 2 times, 1 hour for each time. Conclusion： The optimized process is feasible and stabilization for extraction of salidroside.
