Fatty Acids of Kakheti Regions Grape Rkatsiteli Seed Oils Composition and Their Medical Properties

Abstract

This work covers the problem of fatty acids, contained in Rkatsiteli grape seed oil, raised in 2010-2015 years in Signagi, Kvemo Machkhaani and Telavi regions of Kakheti (East Georgia). The grape seed oil is received by cold press method, quantitative and qualitative analyzed by high-performance liquid chromatography. Saturated, unsaturated and polyunsaturated fatty acids are identified. Their relative concentration is expressed and following physical-chemical constants determined acid number, iodine number, refraction index, specifical weight. The neutral lipids from grape seeds oil are received by extraction. Following free fatty acids are identified: palmitic, stearic, linolic, linolenic, oleic and arachinic. The predominant fatty acids of grape seeds oils, collected in Kvemo Machkhaani and Signagi regions is linolic and oleic acids. In Telavi region also palmitic acid. The integrated investigation demonstrated that fatty acids composition of Rkatsiteli grape seed oils, raised in 2010-2015 years in Kakheti different regions is not identical. Investigation of biological active components of grape seed oil, growing in different regions of Georgia is actual problem.
