摘　　要：以黄姜为原料,采用磨浆预处理后超声提取的方法从黄姜中提取薯蓣皂甙元,考察了磨浆时间、超声提取时间、乙醇浓度、料液比和提取次数对皂素收率的影响,并通过响应面法建立了皂素收率和磨浆时间、超声时间及料液比之间的关系,得到了提取过程优化的工艺条件:磨浆时间5min,超声时间48min;料液比1:18g/ml,拟合得到的模型较好的符合实际,与传统的薯蓣皂素提取方法相比,收率提高了19%。该方法具有收率高、产品纯度高、污染小、节约能源的特点。Diosgenin was extracted by grinding starch pretreatment and ultrasonic extracting method from Dioscorea zingiberensis C.H.Wright. The effects of grinding starch time, ultrasonic extraction time, ethanol concentration, ratio of material to solvent and number of extractions times on extraction yield were investigated. By employing response surface methodology, the relationship of grinding starch time, ultrasonic extraction time, ratio of material and solvent and extraction yield was founded. The parameters of extraction process were optimized, so the optimal experiment parameters are： grinding starch time 5 min, ultrasonic extraction time 50 min and the ratio of material and solvent 1：18, extraction yield of ultrasonic wave extraction method increased 19% compared with the traditional method. The method is energy-saving, of low pollution and better efficiency.
