The fatty-acid composition and some volatile components of essential oil extracted from the leaves of European olive (Olea europaea), growing in the conditions of a dry subtropical climate of the Mediterranean type of the Southern Coast of the Crimea, were determined. 11 fatty acids were found, including monounsaturated and polyunsaturated ones, the composition and ratio of which are similar to the lipid profile of oil from freshly harvested olive fruits. Among the fatty acids, the leading position is occupied by cis-9-oleic (35.07%), palmitic (32.88%) and stearic (10.21%) ones, a significant content of polyunsaturated (cis-9.12-linoleic (9.2%) and cis-12.15-linolenic (6.7%) acids, which determine the nutritional value of the leaves, was also revealed. Among the volatile components of the essential oil of the leaves, 4 aldehydes (pentanal, isobutanal, isopentanal, hexanal) and n-octane, which belongs to the class of alkanes, were determined. The major components of the essential oil are pentanal (valeric aldehyde) and isobutanal (isobutyraldehyde), the mass fraction of which is 60.5% and 22.1%, respectively, which determines the pharmacological value of the leaves.
