Determination of Total Antioxidant Capacity, Radical Scavenging Activity and Fatty Acid Composition of Ultrasonic Assisted Ethanolic Extraction of Oat (Avena sativa L.) Grains
Abstract
In this study, it was aimed to determine the total antioxidant capacity and free radical scavenging activity of the extracts obtained by ultrasonic assisted extraction of oat grains, as well as to determine the fatty acid profile and total tocopherol content of oat extracts. For this purpose, we determined the total antioxidant capacity of oat grains extracts according to the copper ions (Cu2+) reducing antioxidant capacity (CUPRAC) test. At the same time, the radical scavenging capacity of oat extracts was investigated by the 1,1-diphenyl-2-picryl-hydrazil (DPPH•) method. Fatty acid composition of oat extract was determined via GC-FID analysis. Total tocopherol content was determined spectrophotometrically. The total antioxidant capacity of the oat grain extract was calculated as 1.5 ± 0.03 mmol TR 100g-1-oat grains extract by CUPRAC method. The DPPH• radical scavenging activity of the oat extract was calculated as 2.02 ± 0.01 mmol TR 100 g-1 – oat extract. Oat extracts exhibited potent antioxidant and radical scavenging ability. GC-FID results revealed that oat extract was rich in unsaturated fatty acids (Oleic acid, 43%; Linoleic acid, 34%). Total tocopherol content of oat oil extracts was 1376.3 ± 16 mg kg-1-oat extract.
