Mam. Zeitoun et al., VOLATILE, FATTY-ACID AND TRIACYLGLYCEROL COMPOSITION OF EGYPTIAN MANDARINE PEEL OIL, Revue francaise des corps gras, 41(1-2), 1994, pp. 21-22
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.
