Determination of Antioxidant Capacity, Total Phenolic Content and Phenolic Acid Profiles of Some Wild Fruit

In this study, it was aimed to determine the phenolic substance profiles and antioxidant activities of wild fruit species such as, wild pear, hawthorn, cornelian cherry, firethorn which grow naturally in Turkey. For this purpose, the samples dried in the drying oven has been used in extraction. Total phenolic content was determined by FCR method, antioxidant capacity was determined by DPPH, CUPRAC, ABTS and β-carotene bleaching methods. The phenolic profiles of the fruits were illuminated by HPLC. Total phenolic content of the fruits was determined as 493 (wild pear), 847 (hawtorn), 823 (cornelian cherry), 2555 (firethorn) mg GAE/100 g. The results of antioxidant capacity of the wild pear, hawtorn, cornelian cherry and firethorn were determined as 12.275, 22.754, 47.705, 83.134 %TAC in DPPH method, 0.258, 0.619, 0.684, 2.871 mmol TE/g in CUPRAC, 73.78, 49.33, 51.56, 79.34 % TEAC in ABTS and 93.63%, 96.67%, 88.70%, 97.18% in β-carotene bleaching method, in respect. The fruits mainly contain chlorogenic acid, caffeic acid, vanillic acid and synapic acid.
