目的:优选晕宁颗粒提取工艺。方法:用正交设计试验优选水和醇提工艺条件。结果:乙醇提取的最佳条件:8倍量70%乙醇提取3次,每次2 h;水提取的最佳条件:加10倍量水,浸泡0.5 h,提取2次,每次1.5 h。结论:本工艺稳定可行,为晕宁颗粒提取工艺的优选提供了依据。 Objective: To optimize the particle extraction process of Ningning. Methods: Optimum conditions of water and alcohol extraction by orthogonal design test. Results: The optimum conditions of ethanol extraction were as follows: 8 times the amount of 70% ethanol extraction 3 times, each time 2 h; water extraction optimum conditions: plus 10 times the amount of water, soaked 0.5 h, extracted twice, each 1.5 h. Conclusion: The process is stable and feasible, which provides the basis for the optimization of the particle extraction process of Yunning.
