| Background The nutritional value and health-promoting properties cause the fruits (acorns) of Quercus ilex to have great potential for use in the food industry as functional ingredients and antioxidants source. Objective In this study, the amount of total phenolic compounds, flavonoids in different extracts (defatted, non-defatted) and composition of fatty acids in the fruits oils of Quercus ilex were investigated. Besides, antioxidant activity was determined. Material and Methods Fatty acids were extracted with n-hexane and determined by gas chromatography with mass spectrometry detection (GC-MS). Total phenolic and flavonoids contents in the extracts were measured spectrophotometrically and the antioxidant activities were tested by the DPPH (2,2-diphenyl-1-picrylhydrazyl), free radical scavenging assay, free radical-scavenging ABTS and total antioxidant capacity. Results The amount of total phenolic and flavonoid compounds in the defatted Q. ilex were 634.36±27.41 mg GAE/g DW and 96.85±2.13 mg RE/g DW, respectively. Unsaturated fatty acids were detected in higher amounts than saturated fatty acids. The primary unsaturated fatty acids of the Quercus ilex oil were oleic acid (65.38%), 9,12-octadecadienoic acid (16.64%) and palmitic acid (12.81%). Besides, defatted Q. ilex extract showed remarkable DPPH and ABTS radical scavenging activity with IC50 values of 0.008±0.0008, 0.005±0.001 mg/ml respectively, while high total antioxidant capacity of the non-defatted extract with VCEAC value 0.13±0.006. Conclusions Q. ilex oil contained high amounts of polyphenols, high essential fatty acids and antioxidant potential for producing … |
