Influence of abiotic factors on the formation of fatty acid composition of oil in sea buckthorn fruits (Hippophae rhamnoides L.)

The fatty acid composition of oil in the hypanthi-um and seeds of the fruits of wild-growing sea buckthorn forms from the different regions of cultivation have been determined. The general abiotic factors are soil and climatic. They do not have a significant effect on the quality characteristics of oil in the seeds, alternatively to hypanthium. We founded out the content of individual fatty acids and the degree of oil unsaturation in the hypanthium of sea buckthorn from the different ecological and geographical regions differed significantly. The dominant fatty acids of fruit pulp oil are palmitic (C 16: 0) and hexadecene (C 16: 1), the proportion of which reaches 80% of the total FA. Unsaturated acids predominate in seed oil: oleic (C 18: 1), linoleic (C 18: 2) and linolenic (C 18: 3); their total content is 87-90%. This ratio of fatty acids determines the differences in the degree of unsaturation and quality of oil in each of these organs.
