摘要

The lipid extract from hazelnuts was classified as polar (glycolipids = 1.4% and phospholipids = <1%) or nonpolar (triacylglycerols = 98.4%) by column and thin-layer chromatography. Fatty acids derivatized as methyl esters were analysed by GC with flame ionization detector and MS. Oleic acid was predominant in all lipid classes, followed by linoleic, palmitic and stearic. Myristic, palmitoleic, hexadecadienoic, linolenic, eicosanoic and eicosenoic acids were also present in minor proportions. Monoenoic fatty acids predominated in nonpolar lipids, whereas saturated and polyenoic fatty acids were more prominent in polar lipids. Fatty acid contents were compared by ANOVA. Significant differences were found for fatty acid contents in the different lipid classes. A negative correlation was found between monoenoic-polyenoic and monoenoic-saturated fatty acids.
