Apart from its advantage of a single direct extraction pro-cess, ultrasound has also found its coupling use with otherextraction methods. When coupled with a vacuum distillationprocess for the extraction of flavor compounds from varieties of Mentha spicata, it produced extracts with higher flavoringstrength compared with hydro-distillation (Porto and Decorti,2009). In combining ultrasound with agitated bed extraction, ithas resulted higher total phenolic yields from Jabuticaba com-pared to sole ultrasound-assisted extraction or agitated bedextraction for a same extraction time of 2 h (Santos et al.,2010).
