Analysis Fatty Acids of some Hyoscyamus , Datura , Atropa Species from Azerbaijan Azerbaycan ' dan Bazı Datura , Hyoscyamus , Atropa Türlerinin Yağ Asitlerinin Analizi

INTRODUCTION: Datura stramonium, Datura stramonium var. tatula, Hyoscyamus reticulatus, Hyoscyamus niger, Atropa caucasica naturally found in Azerbaijan and their seeds possess 1735% of oils. Study aim to evaluate and determine fatty acids of these plants special for Azerbaijan climate and geography. The presented study is the first research of fatty acids of A. caucasica, which is an endemic species of Caucasus. METHODS: Fatty acids of seed oils were derivatized to methyl esters and analyzed by gas chromatography equipped with a flame ionization detector, in comparison with a standard mixture of 37 fatty acid methyl esters RESULTS: Linoleic (55-79%), oleic (11-26%), palmitic (4-12%) and stearic (2-3%) acids compose 97% of total fatty acids. Other minor compounds, including 2 trans fatty acids, were determined in the samples. Significanty high consentration of a medicinaly important polyunsaturated fatty acid linoleic acid was observed in all samples. DISCUSSION AND CONCLUSION: The results of this study showed that these oils are especially valuable sources of linoleic and oleic acids, which have beneficial effects on cardiovascular diseases and are important compounds for the pharmaceutical and cosmetic industries in the manufacture of liposomes, nanoand microemulsions, soaps, etc.
