目的优选咽炎合剂I号口服液的提取工艺。方法以黄芩苷含量和浸膏得率为指标,采用L9(34)正交试验对提取工艺进行优选。结果最佳提取工艺为10倍量水,煎煮90 m in,煎煮3次,60%乙醇沉淀。结论所优选的最佳提取工艺可行。
Objective To optimize the extraction process of pharyngitis mixture I oral solution. Methods Based on the content of baicalin and the yield of the extract, the extraction process was optimized by L9 (34) orthogonal test. Results The best extraction process was 10 times the amount of water, boiling 90 m in, boiling 3 times, 60% ethanol precipitation. Conclusion The best extraction process is feasible.
