In this study, the extraction conditions to maximize the antioxidant activity and total phenolic content of Ficus auriculata were optimized using response surface methodology. For the purpose of extraction, the Ultrasonic assisted extraction technique was employed. A second-order polynomial model satisfactorily fitted to the experimental findings concerning antioxidant activity (R2 = 0.968, P<0.0001) and total phenolic content (R2 = 0.961, P<0.0001), indicating a significant correlation between the experimental and expected value. The highest antioxidant activity (85.20 ± 0.96 %) for DPPH were achieved at the optimum extraction parameters of 52.5% ethanol (v/v), 40.0 °C temperature, and 22 min extraction time. Alternatively, the highest yield of total phenolic content was found 31.65 ± 0.94 mg GAE/g DF at the optimum extraction conditions. From the LC-ESI-MS profiling of the optimized extract, 18 bioactive compounds were tentatively identified, which may regulate the antioxidant activity of fruits of F. auriculata.
