目的:优选腰痛颗粒剂中生物碱的最佳提取工艺。方法:采用正交试验法,以干浸膏得率、防己总碱和粉防己碱提取率为考察指标,优选总生物碱的渗漉工艺。结果:确定了最佳工艺条件为粉碎度为粗粉、乙醇浓度为60%、浸泡时间为48h,渗漉速度为2 ml·min-1·kg-1。结论:该工艺简便、快捷、稳定,可为生产提供理论依据。
Objective: To optimize the extraction process of alkaloids from Yaowong Granules. Methods: Orthogonal test was used to study the yield of dry extract, the extraction rate of total alkaloids and tetrandrine, and the total alkaloid percolation process was optimized. Results: The optimum technological conditions were determined as coarse powder, ethanol concentration of 60%, soaking time of 48h, percolation rate of 2 ml · min-1 · kg-1. Conclusion: The process is simple, fast and stable, which can provide a theoretical basis for production.
