| Abstract | Field corn cobs, a major agricultural byproduct, are rich in phenolic compoundswith antioxidant potential. The aim of this study was to optimize phenolic extraction from field corn cobs using ethanol and ultrasound-assisted ethanol extraction (UAE).Compared to conventional extraction, UAE improved efficiency while reducing time.The optimal condition for phenolic extraction was using UAE with 50% ethanol, 37kHz frequency, 50°C, and 60 minutes. The field corn cob extract showed the highest total phenolic content at 1125.38 µg GAE/g CC, and the inhibitory concentration (IC50) of DPPH was 2.48 mg/mL. Even though the IC50 value of field corn cob extract is higher than that of ascorbic acid (29.16 µg/mL). This research highlights the sustainable use of corn cobs as a natural antioxidant source for industrial applications. |
