This study was conducted to investigate the antioxidant activity and total phenolic compounds of the Moringa oleifera leaves. Ultrasonic assisted extraction (UAE) technique was employed with methanol as a solvent. The temperature and sonication time were varied from 30 to 45°C and 10 to 30 min, respectively at fixed ultrasonic power of 560 Watts. A 1,1 -diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and Folin – Ciocalteu assay were used to determine the antioxidant activity and total phenolic content (TPC), respectively. The extracts obtained showed changes in the antioxidant activity and total phenolic content that with the increased of extraction temperature and sonication time. The highest antioxidant activity of 72.44 ± 0.0575 % and phenolic content of 328.87 ± 0.0516 mg (GAE)/mg) were obtained at 45℃ and 30 min, respectively. Hence, UAE is suitable to extract bioactive compounds from Moringa oleifera leaves and thus, can become an alternative for antioxidants processing method.
