%X The aim of this study was to determine the fatty acids, sterols and triacylglycerol compositions as well as the amount of tocopherols, total phenols and pigments wild almond and cold pressed wild pistachio oils. Triacylglycerols, tocopherols and pigments were analyzed with HPLC, fatty acids and sterols with gas chromatography, and total phenols photometrically. The main fatty acids in both samples were oleic, linoleic and palmitic acids. The most predominant TAG species are SLL + PLO (21.83%) in wild pistachio oil and OOO (47.27%) in wild almond oil. Pheophytin a was the major pigment in wild pistachio oil. There were no pigments detected in wild almond oil. Total phenols were 57.6 mg kg-1 oil for wild pistachio and 45.3 mg kg-1 oil for wild almond oil. El objetivo de este estudio fue determinar la composici¨®n en ¨¢cidos grasos, esteroles, triglic¨¦ridos, as¨ª como tocoferoles, fenoles totales y pigmentos de aceites de almendras y pistachos silvestres prensados en fr¨ªo. Triglic¨¦ridos (TAG), tocoferoles y pigmentos se analizaron mediante HPLC, los ¨¢cidos grasos y esteroles mediante cromatograf¨ªa de gases, y los fenoles totales espectrofotom¨¦tricamente. Los principales ¨¢cidos grasos de ambas especies fueron los ¨¢cidos oleico, linoleico y palm¨ªtico. Las especies de TAG predominantes son SLL + OLP (21,83%) en el pistacho silvestre y OOO (47,27%) en almendras silvestre. Feofitina a es un pigmento importante en los aceites de pistacho silvestre. No se detect¨® pigmentos en los aceites de almendras silvestres. Los fenoles totales fueron 57,6 mg kg-1 y 45,3 mg kg-1 en los aceites de pistacho silvestre y de almendra silvestre respectivamente.
