VOLATILE, FATTY-ACID AND TRIACYLGLYCEROL COMPOSITION OF EGYPTIAN MANDARINE PEEL OIL

Volatile, fatty acid, and triacylglycerol components of crude Egyptian mandarine peel oil were determined by dynamic headspace capillary gas chromatography mass spectrometric analysis, capillary gas chromatogra phy, and reversed-phase high performance liquid chromatography with fl ame ionization detection, respectively. Mandarine peel oil contained 1 .8% crude oil, of which 0.6% was triacylglycerol with respect to peel weight. Dipalmitoyllinoleoyl was the most abundant triacylglycerol pre sent at 22.0%. Mandarine peel is currently a waste product of the Egyp tian citrus industry. The fatty acid composition of the triacylglycero l oil was 19.6% palmitic, 2.8% stearic, 12.0% oleic, 55.4% linoleic, a nd 8.9% linolenic. The volatile portion of crude mandarine peel oil co ntained four major components in concentration 10% or greater: 37.4% l imonene, 20.0% gamma-terpinolene, 15.2% beta-myrcene and 9.5% delta-3- carene.
