摘要
目的:对老鹳草总鞣质的提取工艺进行优化。方法:采用L9(34)正交设计,以没食子酸的提取率为考察指标,考察乙醇浓度、提取时间、乙醇用量、提取次数4个因素对提取的影响。结果:优化提取工艺条件为30%乙醇,30倍量,提取3次,每次1h,验证性实验符合标准。结论:该工艺方法稳定、可靠、操作可控,有效成分提取效率较高。
Objective：To optimize the extraction technology of total Tannins of Erodium stephanianum Willd.Methods：The extraction technology optimized by orthogonal Design L9（34）,while Gallic acid were adopted as indexes,Factors of ethanol concentration,reflus duration,ethanol quantity and extraction times were evaluated for their effects on extraction process.Results：The best conditions for the extraction of 30 percent ethanol,thirty times the amount extracted three times,each 1h,experimental verification of compliance.Conclusion：The Process stable and reliable operation reasonable,and effective extraction more efficient.
