目的:优选咽炎清口服液最佳提取工艺。方法:以绿原酸转移率和浸膏得率为综合评价指标,以溶剂量、提取时间和提取次数为考察因素,每因素设计3个水平,用_9(3~4)正交表安排试验。结果:咽炎清口服液最佳提取工艺为加10倍量水回流提取3次,每次1 h。结论:该提取工艺设计合理,结果可靠,提取效果较好,具有较高的应用价值。
Objective: To optimize the best extraction technology of pharyngitis and oral liquid. Methods: Taking the chlorogenic acid transfer rate and the extraction yield as the comprehensive evaluation indexes, taking the solvent amount, the extraction time and the number of extraction times as the investigation factors, three levels were designed for each factor and arranged with the orthogonal table of _9 (3 ~ 4) test. Results: The optimal extraction process of Yanyanqing oral solution was 10 times the amount of water back extraction three times, each time 1 h. Conclusion: The extraction process is reasonable in design, reliable results, good extraction effect, and high application value.
