  Abstract: Ultrasonic-assisted extraction (UAE) parameters were optimized in this study using response surface methodology (RSM) to improve the total phenolic content (TPC), total flavonoid content (TFC), and antioxidant activity assessed using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) assays of Moringa stenopetala leaves. According to the results, the optimal UAE parameters were extraction time (26 min), ethanol concentration (68%), and solvent-to-sample ratio (42 mL/g). Based on these optimal parameters, …
