摘要
目的研究灵香草中总黄酮的最佳提取工艺。方法采用正交实验,考察了溶剂浓度、液料比、提取时间、提取次数对灵香草中总黄酮提取量的影响。结果灵香草中总黄酮最佳提取工艺为60%乙醇,液料比10∶1,提取3次,2h/次。结论该工艺简单易行,是灵香草中提取总黄酮的有效途径。
Objective To study and optimize the extraction technique of the total flavonoids in Lysimachia foenum-graecum Hance.Methods Orthogonal test was carried out to investigate the effects of concentration of solvent,the radio liquid to material,time of extraction,and frequency of extraction on extraction results of total flavonoids from Lysimachia foenum-graecum Hance.Results The optimum extraction technique was to extract Lysimachia foenum-graecum Hance in 60% ethanol with the ratio of liquid to material at 10∶1 3 times,with 2 hours for each time.Conclusion The optimal technique is simple and feasible,and can provide reference for further research of Lysimachia foenum-graecum Hance.
