| dc.description.abstract | The aim of this study was to investigate the effect of drying and extraction methods on phenolic content and antioxidant capacity of the extract from Ficus carica leaves. Total phenolic content and antioxidant capacity were evaluated using Folin-Ciocalteu’s method and DPPH radical scavenging method. Different drying methods (sun-drying, freeze-drying, oven-drying) were tested and sun-drying (273.44 9.48 mg GAE/ 100g dry weight) was chosen as the most suitable method for the next experiments. Five solvents with ethanol-to-water ratio: 0:100, 25:75, 50:50, 75:25, 100:0 were applied to extract sun-died leaf samples and 50% ethanol (268.53 11.99 mg GAE/ 100g dry weight) was picked as the best solvent for extraction. Sets of extraction time applying maceration method (0, 1, 2, 3 hours) and ultrasound method (0, 10, 20, 30, 40 minutes) were tested to find the best durations for extracting Ficus carica leaves. As the result, sun-dried Ficus carica leaves extracted with 50% ethanol for 2 hours of maceration (276.45 6.43 mg GAE/ 100g dry weight) and sun-dried fig leaves extracted with 50% ethanol for 20 minutes of ultrasonication (376.61 5.20 mg GAE/ 100g dry weight) showed the optimal total phenolic content results.
