以葫芦巴种子、风干鲜叶、风干根为原料，建立了微波辅助提取薯蓣皂苷元的方法。研究了提取时间、微波功率、2-丙醇在提取液中的含量及其相互作用，以优化提取效率。后两个参数被认为是最重要的。利用响应面模型对所选基质中薯蓣皂苷元的提取率进行了预测。采用毛细管气相色谱-质谱联用技术对薯蓣粗提物中的薯蓣皂苷元进行了分析。
A focused microwave-assisted extraction method was developed for the extraction of diosgenin from fenugreek (Trigonella foenum-graecum) seeds, air-dried and fresh leaves and air-dried roots. Several experimental parameters were studied, including extraction time, microwave power applied and percentage of 2-propanol in the extraction mixture as well as their interactions, in order to optimize the extraction efficiency. The two latter parameters were found to be the most important. Response surface modelling was used to predict the extraction yield of diosgenin in selected matrices. The analysis of diosgenin in crude extracts was carried out by capillary gas chromatography-mass spectrometry (GC-MS).
