A study of ultrasonically assisted extraction of bioactive principles from Quillaja Saponaria Molina (Quillay) is presented. To address the problem it was studied the effects that could influence the extraction process through a two-level Factorial Design. The effects considered in the Experimental Design were: Granulometry, Extraction time, Acoustic Power and Acoustic Impedance. The production of the quillaja extracts is done with an aqueous extraction and the process is assisted by an ultrasonic field; no other solvents are used in its production. The final product only incorporates natural ingredients and raw materials, authorized for their use in food manufacturing processes. The principal factors affecting the ultrasonic extraction process were: Granulometry and Extraction time. The enhanced of ultrasonic assisted extraction ratio was measuring the increasing yield of extracted components, the extraction ratio was increased by ultrasonic effect and a reduction in extraction time was verified. In addition the process can be carried out at temperatures lower than the traditional way. The influence of ultrasound on the quality of bioactive principles was examined by HPLC technique and no influence of ultrasound on natural components was found.
