Several experimental parameters were studied, including extraction time, microwave power applied and percentage of 2\u2010propanol 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\u2013mass spectrometry (GC\u2010MS).
