Abstract
An ecofriendly ultrasonic-assisted extraction (UAE) technique was developed for rapid extraction of bioactive compounds oleanolic and ursolic acids from blueberry.
Several different influential extraction parameters such as ultrasonic power, extraction time, solvent type, aqueous ethanol concentration, loading ratio and extraction temperature were investigated.
The optimum extraction conditions were 90% ethanol solution as solvent, ultrasound power 150 W, the liquid:material ratio of 20:1 (v/w) and extraction for 60 min at 40°C. The UAE method was more efficient than classical methods included maceration, stirring extraction and heat reflux extraction.
