%X Chokeberry (Aronia melanocarpa L.) contains a large number of bioactive compounds,
which make of it a highly nutritional and antioxidant food with anti-cancer and anti-inflammatory
properties. It has been recently seen its consumption increased because of its interesting composition
and 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, not
only separately but also simultaneously. Multiple response has been optimized and demonstrated
an e ectiveness level similar to the individual ones. This represents a considerable reduction in
costs, time and work. The optimal conditions for simultaneous extractions were: 54% methanol as
extraction solvent at pH 2.72 and 69.4  C temperature, 70% amplitude, 0.7 s cycle, and 0.5:18.2 g:mL
sample mass/solvent volume ratio. The developed methods showed a high precision level with
coe cients of variation lower than 5%. The methods were successfully applied to commercial
samples. Additionally, the extraction of other compounds of biological interest, such as organic acids
and sugars, was also studied.
