摘要：The aim of this study was to perform a screening for the hydrodistillation process parameters in order to attain the highest possible yield of peppermint essential oil. The screening process was carried out by a Placket and Burman design. After the choice of seven variables, sixteen experiments were executed. The data analysis has permitted to identify a first-order polynomial model relating the response (essential oil yield) to the studied factors. After the validation of the fitted model, the results allowed us to conclude that five factors (the extracting time, the individuality effect, the material/water ratio, the harvest period and the heating temperature) have a significant effect on the hydrodistillation process. However, the plant material's drying and cutting present a statistically negligible effect.
