Abstract:
In this study, black and white seed of Salvia hispanica L., known as chia, which is of Argentina origin and has commercial value in our country, was used. The fixed oils in chia seeds were obtained by using both conventional and modern techniques and their chemical profiles were evaluated comparatively. In this respect, conventional techniques; cold pressing, Folch and continuous solvent extraction techniques were used. Modern techniques; fixed oils were obtained using accelerated solvent extraction and supercritical fluid extraction techniques. The chemical profiles of all fixed oils obtained were determined by both Gas Chromatography-Flame Ionisation Detector/Mass Spectroscopy (GC/FID-MS) method and ultra performance convergence chromatography (UPC 2 ) method for the first time. Total phenol content of methanol extract obtained from Salvia hispanica L. seeds was determined by using Folin-Ciocalteu reagent equivalent to gallic acid. The total amount of flavonoids in the extracts was determined by using AlCl 3 reagent equivalent to routine and quercetin. DPPH, TEAC and ORAC assay were used to determine the antiooxidant capacity of chia seed extracts obtained by different extraction methods.
