仙鹤草降糖活性成分提取工艺优化
摘要
目的:仙鹤草降糖活性成分提取工艺的优选。方法:以提取物降糖活性为指标
采用L9(34)正交设计实验
考察了乙醇浓度、提取时间、料液比、提取温度对提取率的影响
优选出合理的提取工艺。结果:优选出仙鹤草降糖活性成分的最佳提取工艺条件是:回流提取3次
1 h/次
60%乙醇溶液
料液比1∶10
提取温度为80℃。结论:优化后的工艺提取率高。
Abstract
Objective:To optimize the extraction condition of lowering blood sugar substance from agrimony.Method:With effects of lowering blood sugar as criteria
concentration of alcohol
extraction time
and the ratio of gardenia to liquor and extraction temperature are evaluated by L9(34) orthogonal design method.Result:The opti-mum extraction condition was described as follow:hot reflux extraction 3 times(once 1 hour)
60% ethanol solu-tion
and 10-fold solvent.Conclusion:The high extraction rate is got at the optimum technology.
