Lipids of elaeagnus fruit

The composition of the classes of lipids of the fruit of three morphological forms of the elaeagnusElaeagnus angustifolia L. have been studied. Their compositions were identical. The amounts of the main lipid classes of extracts of the seeds and pericarps, the fatty acid compositions of the acyl-containing classes of lipids, and the compositions of the carbohydrates and sterols have been determined. The fatty oil of the seeds contained linoleic acid, while the main fatty acids of the pericarp extracts were the 16:0, 18:1, and 18:2 acids. The 16:1 acid that is characteristic for sea buckthorn oil was detected in the elaegnus fruit in insignificant amounts. The class of sterols, both in the free and in the esterified states, was represented by β-sitosterol. The main hydrocarbon of the pericarps and seeds was nonacosane.
