Cotton is the main source of natural fiber worldwide, also seeds to process oil and meal. The fatty acids profile as the part of metabolomics profile of seeds studied in cotton accessions belong to Gossypium hirsutum L. (Upland), G. herbaceum L. (diploid), G. barbadense L. (Pima cotton) grown in South of RF. Gas-liquid chromatography and mass-spectrometry used. The digital peaks identification performed by mass spectrum libraries. The research aim was to characterize fatty acids profile of seeds, to select the best cotton cultivars accessions, valuable in seed biochemistry compound. Considered as a part of metabolomics profile linolenic acid tested in greatest amount among other fatty acids. The mean amount reached 117.2 mg 100 g −1 of seed among all studied varieties. The maximum amount reported in Abolin CFN variety, G.hirsutum (197.4). The content of di-unsaturated linoleic acid in Fors and Voitenok FRT reached 186.2 and 85.7 mg 100 g −1 respectively, and Tiamin 82.6 (G. barbadense). Oleic acid mean amount estimated as 70.9, which maximum contents detected in cultivars Cumbazic Maron (naturally colored fiber) and Fors. Improvement of biological activity of cottonseed oil, meals and cakes as well is in focus to implement the trend of healthy food and high-quality feed.
