It has been recently seen its consumption increased because of its interesting compositionand properties as a functional food. The ultrasound-assisted extraction method has been optimized,since it is a simple and fast technique to extract phenolic compounds, as well as anthocyanins, notonly separately but also simultaneously. Multiple response has been optimized and demonstratedan e ectiveness level similar to the individual ones. This represents a considerable reduction incosts, time and work. The optimal conditions for simultaneous extractions were: 54% methanol asextraction solvent at pH 2.72 and 69.4 C temperature, 70% amplitude, 0.7 s cycle, and 0.5:18.2 g:mLsample mass/solvent volume ratio. The developed methods showed a high precision level withcoe cients of variation lower than 5%. The methods were successfully applied to commercialsamples. Additionally, the extraction of other compounds of biological interest, such as organic acidsand sugars, was also studied.
