目的:探讨养阴清热降糖胶囊的最佳提取工艺。方法:采用正交设计优化养阴清热降糖胶囊的水提取工艺,以多糖含量为考察指标,比较溶剂用量、提取时间及提取次数对提取效果的影响。结果:最佳提取条件为8倍水量,回流提取3次,每次1h。结论:该工艺所得多糖含量较高,稳定性、重复性较好,可为养阴清热降糖胶囊的制备提供参考资料。
Objective: To explore the best extracting technology of Yangyin Qingre hypoglycemic capsule. Methods: Orthogonal design was used to optimize the water extraction process of Yangyin Qingre Jiangtang Capsules. Polysaccharide content was taken as the index of investigation. The effects of solvent dosage, extraction time and extraction times on extraction efficiency were compared. Results: The optimum extraction conditions were 8 times the amount of water, reflux extraction 3 times, each time 1h. Conclusion: The polysaccharide content of the process is higher, stability, repeatability is good, can provide reference for the preparation of yin nourishing hypoglycemic capsule.
