Lipid composition of viburnum and barberry fruits

Abstract

The objects of the study were the fruits of viburnum vulgaris (Viburnum opulus L) and barberry (Berberis vulgaris). Powders were obtained from fresh viburnum and barberry fruits by convective drying. The lipid complex of powders from viburnum and barberry fruits was studied. The total content of lipids in barberry powder was determined to be 7.6%, and in viburnum powder–7.1%.The group composition of lipids of powders, which is represented by neutral and polar lipids, was examined. The main part of lipids is triglycerides. Unsaturated fatty acids (LC) predominate in the composition of lipids of powders. Barberry powder contains essential fatty acids, such as linoleic–35.54% and linolenic–35.60%, which indicates a high biological efficiency of barberry lipids, viburnum powder has 46.56 % of oleic acid and 46.14 % of linoleic acid. The fractional composition of sterols of viburnum and barberry powders was studied. It was revealed that the fractional composition of viburnum powder sterols contains more fractions than the sterols of barberry powder.7 fractions were identified in the composition of viburnum powder sterols: campesterol, beta-sitosterol, beta-amyrin, stigmasta-5.24(25) - dien-3-ol, alpha-amyrin, cycloartenol, citrostadienol. The predominant fractions are alpha-amyrin, beta-amyrin, and beta-sitosterol. 3 fractions were identified in the composition of barberry powder sterols: campesterol, beta-sitosterol, delta-5-avenasterol, the main fraction is beta-sitosterol.
