Peanut (Arachis hypogaea L.) oil from seeds of six varieties; boro red, boro light, mokwa, ela, campala and guta as well as oil from three geographical zones in Nigeria; northern, eastern and western were investigated. Gas chromatography analysis showed high concentrations of oleic and linoleic acids in the oil samples. Capric (0.0%) and Lauric (8.1%) acids were absent and highest, respectively in the mokwa variety and hence diagnostic. More so, the comparative chemical analysis of peanut oil from the three zones and some selected refined vegetable oil; sunola, grand, olive and corn oil, indicated that western and grand oil had high iodine value 1.74±0.1 and 2.63±0.1, respectively, compared to others. The northern oil had high acid and fat value than the others (4.49 and 133%, respectively). Furthermore, the saponification value of the local vegetable oil was found to be significantly higher than the refined vegetable oil (P < 0>
