正交试验法优选咽舒宁颗粒剂的提取工艺

Optimization of the extraction technology of Yanshuning granules by orthogonal test method

目的优选咽舒宁颗粒剂的最佳提取工艺。方法以提取液中表告依春和哈巴俄苷含量、干膏得率为指标,用正交试验法,优选提取工艺条件。结果最佳提取工艺为:加8倍药材质量的水,提取3次,每次1h。结论此提取工艺合理可行,适合工业化生产。

Objective To optimize the extraction technology of Yanshuning (traditional Chinese medicine)granules. Methods Using the contents of epigoitrin and harpagoside in the extract solution and the yield of the dried extracts as the criteria,orthogonal test method was used to optimize the conditions for the extraction process. Results The optimal extraction process for Yanshuning granules was to add 8 times of water to the medicinal herbs,decoct for 3 times and 1 hour each time. Conclusion The extraction technology is reasonable,and can be used for industrial production.
