Summary. The article presents the results of the study of the fatty acid spectrum of Nigella sativa L. seed oil grown in different geographical regions – Ukraine and Bulgaria. The task of studying the rich chemical composition of the plant due to the wide range of its pharmacological action remains relevant.
The aim of the study – comparative study of the fatty acid composition of Nigella sativa L. seed oils grown in different geographical and climatic regions.
Materials and Methods. Nigella sativa L. oil samples were obtained from 2 different geographically remote regions, Ukraine and Bulgaria; various producers: black seed oil (Zhestor, Ukraine) and Black seed oil (Zdravnytsia, Bulgaria).Gas chromatography was used to study the fatty acid composition of Nigella sativa L.
Results. It was found that the composition of both studied samples includes 9 fatty acids: lauric, arachic, palmitic, palmitoleic, myristic, pentadecene, oleic, stearic and pentadecanoic. The content of oleic acid in the oil of the Ukrainian producer was twice as high as in the oil of the Bulgarian production. Also, the content of pentadecanoic acid in the oil of domestic sample was insignificant (0.03 %). The percentage of the other seven fatty acids found differed slightly in the oils studied. This may indicate a slight difference in growth conditions and, as a consequence, the chemical composition of Nigella sativa L.
Conclusions. The geographical and climatic region in which Nigella sativa L. is grown plays an important role in the formation of its chemical composition and this leads to changes in its pharmacological activity. However, the results obtained indicate that the difference in the relative content of fatty acids between the studied oils of Ukrainian and Bulgarian producers is insignificant.
