A comparative analysis of oil content and fatty acid in different varieties of Arachis hypogaea L. from Turkey

Abstract

The aim of the study is to investigate the composition of the oil content and the fatty acids in different varieties (i.e. NC-7, Batem-5025, Osmaniye-2005, Sultan, and Halisbey) of peanut (Arachis hypogaea L.) grown in the province of Osmaniye in Turkey. Batem-5025 provided the greatest percentage of oil with 50.30%. Higher concentrations in oil specimens were found for oleic and linoleic acids. The fatty acids in the all varieties were oleic (51.32-62.43%), linoleic (18.27-27.54%), palmitic (8.35-9.69%), stearic (2.64-3.36%), behenic (2.56-2.85%), arachidic (1.43-1.62%), and lignoceric (1.15-1.53%) acids listed in order of concentration. The saturated fatty acids were observed to be far less than the unsaturated ones (80.07-81.88%) in any of the varieties. The varieties of NC-7 and Osmaniye-2005 had oleic and linoleic acids at the highest concentration and stearic and palmitic acids at the lowest, respectively. NC-7 showed the best oleic-to-linoleic (O/L) ratio with 3.41.
