Abstract

A new method for extracting oleanolic acid from olive leaves, characterized in that olive leaves, previously degreased by means of a suitable solvent, such as an open or closed chain ether, are halogenated solvents or the like, or in certain cases, without previous degreasing, the oleanolic acid and its derivatives are extracted by maceration in a solution which is concentrated, making it precipitate by the addition of petroleum ether, hexane, heptane or the like, and then more alcohols are then crystallized in ether solutions.
