Abstract
Process for the recovery of oleanolic and maslinic acids contained in the subproducts resulting from the milling and processing of olives or parts thereof, either proceeding from three-phase or two-phase presses. This process enables to obtain, by separation and with purities higher than 80%, of both acids with yields comprised between 0.2 and 1.5%, as a function of the product and prime material processed. Fundamentally, it comprises selective extractions and fractionation of resulting mixtures with the use of solvents.
