GC and GC/MS analyses of the diethyl ether washings of fresh grapes of Vitis vinifera x (Vitis labrusca x Vitis riparia) interspecific hybrid Othello from Serbia enabled the Identification of 39 constituents that accounted for 96.5% of the total GC peak areas. Five major contributors were the following: heptacosane (15.0%), hentriacontane (15.0%), ethyl oleate (12.4%), nonacosane (11.0%) and pentacosane (8.3%). n-Alkanes (50.9%), fatty acid ethyl esters (32.2%) and higher aldehydes (7.7%) alone constituted 90% of the extract. Ethyl (E,Z)-2,4-decadienoate, ethyl hexacosanoate, ethyl tetracosanoate, ethyl docosanoate, octane and undecane are reported for the first time as grape constituents.
