正交实验优化黄蒿消炎颗粒的乙醇提取工艺研究
Orthogonal optimization of the ethanol extraction technology for Huanghaoxiaoyan Granules
目的：对黄蒿消炎颗粒的乙醇提取工艺进行优化。方法：采用正交试验法，以欧前胡素的含量和干浸膏收率为考察指标，对乙醇浓度、提取时间、提取次数和溶剂用量等4个因素进行研究。结果：最佳工艺为用8倍量的60%乙醇回流提取3次，每次1.5h。结论：应用该工艺提取效率高，合理、稳定可行，适合工业化生产。
o optimize the ethanol extraction technology for Huanghaoxiaoyan Granules. Methods: Orthogonal test was adopted in the study. on the ethanol concentration, extraction time, extraction times and solvent dosage of 4 factors, and the rate of harvesting of the extract, the contents of ammidin were used as indices of appraisal. Results: The best technology for the use of 8 times 60% ethanol and extracted three times, each time 1.5h. Conclusion: The application of the extraction process is efficient,reasonable and practicable, suitable for industrial production.
