【摘要】 目的:确定竹节三七齐墩果酸型皂甙的最佳水提取工艺条件。方法:采用单因素试验设计与正交试验设计L9(34)方法,考察浸提时间、浸提温度、固液比和浸提次数等因素对提取率的影响,优选出竹节三七中齐墩果酸的提取工艺。结果:所考察的因素对竹节三七齐墩果酸型皂甙提取的影响程度为:浸提温度>浸提次数>固液比>浸提时间,水浸提取的最佳条件为:A3C3D3B2。结论:优选出的竹节三七中齐墩果酸的提取工艺稳定、合理、可行。更多还原

【Abstract】 Objective:To optimize the aqueous extraction condition for oleanolic acid saponins in Panax japonicus C.A.Mey.Method:Orthogonal test L9(34) is designed on single factor experiment,the optimum aqueous extraction technique is sought through experimental investigation.Result:The order of factors to affect the oleanolic acid extraction is first the soaking temperature,second the soaking times,third the ratio of solid to liquid,finally the extraction time.The optimum aqueous extractions were A3C3D3B2.Conclusion:The optimized extraction process is stable,reasonable and feasible.更多还原
