摘要
目的:优选天宁颗粒提取工艺条件。方法:以乙醇浓度、乙醇用量、提取时间和提取次数为考察因素,以天麻素、阿魏酸的含量,以及干膏率为评价指标,采用正交试验优选最佳工艺条件。结果:最佳工艺条件为乙醇浓度为75%,8倍量乙醇,提取2次,每次1.5 h。结论:该提取工艺稳定可行,可用于天宁颗粒的提取。
Objective：To study the technological parameters of the extraction process of Tianning granules.Method：The ethanol concentration and amount,the extraction time and times as the testing factors,the contents of gastrodin and ferulic acid determined by HPLC and dry extract yielding rate as the evaluation indices,the optimal technological parameters were screened by orthogonal design. Result：The optimal parameters were as follows;8 times 75%ethanol as the solvents,the raw material was extracted twice with 1.5 h for each time.Conclusion：The process is steady and feasible,and can be used in the extraction of Tianming granules.
