摘　　要：目的:优选宣木瓜总皂苷的提取工艺。方法:以宣木瓜总皂苷得率为评价指标,通过单因素试验筛选提取方法,利用正交试验考察乙醇体积分数、提取温度、料液比及提取时间对宣木瓜总皂苷提取工艺的影响。采用UV测定总皂苷含量,检测波长550 nm。结果:最佳乙醇提取工艺为加20倍量80%乙醇于90℃提取3 h;宣木瓜总皂苷得率1.69%。结论:优选的提取工艺稳定可行,为宣木瓜系列产品的开发提供参考。Objective：To optimize extraction process of total saponins from Chaenomelis Fructus.Method：Taking yield of total saponins as index,extraction method was selected by single factor test,orthogonal test was adopted to optimize extraction process with ethanol concentration,extracting temperature,ratio of material to liquid and extraction time as factors.UV was employed to determine the content of total saponins with detection wavelength at 550 nm.Result：The best extraction process was as following：extracted 3 h with 20 times the amount of 80％ ethanol at 90 ℃ ; yield of total saponins from Chaenomelis Fructus was 1.69％.Conclusion：This process was stable and feasible,it could provide a reference for development of series products of Chaenomelis Fructus.
