目的:优选新滋谷片的最佳提取工艺。方法:采用出膏率及总黄酮的含量为评价指标,以正交试验法L9(34)优选提取工艺参数。结果:乙醇浓度为主要影响因素,其余均为次要因素,确定最佳工艺为:加70%乙醇8倍量,提取2次,每次提取1h。结论:优选的提取工艺稳定,可行。 Objective: To optimize the extraction process of Xinzigu tablets. Methods: Using the rate of ointment and the content of total flavonoids as evaluation indexes, the optimum extraction parameters were obtained by orthogonal experiment L9 (34). Results: Ethanol concentration was the main factor, and the rest were secondary factors. The optimum process was determined as follows: adding 70% ethanol 8 times, extracting 2 times and extracting 1 h each time. Conclusion: The optimal extraction process is stable and feasible.
