The invention relates to a method of preparing a wide range of hydroxytyrosol esters. According to the invention, the compounds are synthesised by reacting synthetic hydroxytyrosol or natural hydroxytyrosol compounds, oleuropein or oleuropein aglycones (which are found in olive oil, vegetable water, olive marc or olive leaves) with an acylating agent which is a compound containing at least one acylic group R, wherein R is H, an alkyl radical with between 1 and 31 linear, branched or cyclic carbon atoms, an alkenyl radical with up to 31 linear, branched or cyclic carbon atoms or an aryl group. The invention also relates to the esters prepared with the inventive method, which can be used as an additive in food and cosmetic products as well as in pharmaceutical preparations.
