The aim of this work was separation and determination of oil from the walnut cultivar Sampion. Two techniques of oil extraction were employed: cold pressing and organic solvent extration. Composition of walnut kernels and basic physico-chemical parameters of walnut oil were determined, respectively. The oil content was 69.07%. The fatty acid composition was determined by gas chromatography and the main components were as follows: linoleic acid 58.0%, oleic acid 20.7%, and linolenic acid 9.8% for sample obtained by cold pressing and 60.9%, 19.0%, and 13.6%, respectively, for sample obtained by solvent extraction.
