  • Method for obtaining purified hydroxytyrosol from products and by-products derived from the olive tree
    Patent number: 6849770
    Abstract: The present invention relates to a method for obtaining purified hydroxytyrosol from products and by-products derived from the olive tree by means of two-step chromatographic treatment. The invention uses a non-activated ion exchange resin chromatographic method, followed by a second treatment on an XAD-type absorbent non-ionic resin which concentrates and completely purifies the hydroxytyrosol by means of elution with a methanol or ethanol:water dissolution (from 30 to 33%). The method of the invention can also be applied to two-phase pomaces, three-phase pomaces and stones if they are subjected to a steam explosion process.
