This study focused on the biological evaluation and chemical characterisation of Ficus sur Forssk. (F. sur) (Family: Moraceae). The methanolic and aqueous extracts' phytochemical profile, antioxidant, and enzyme inhibitory properties were investigated. The aqueous stem bark extract yielded the highest phenolic content (115.51 +/- 1.60 mg gallic acid equivalent/g extract), while the methanolic leaves extract possessed the highest flavonoid content (27.47 +/- 0.28 mg Rutin equivalent/g extract). In total, 118 compounds were identified in the tested extracts. The methanolic stem bark extract exhibited the most potent radical scavenging potential against 2,2-diphenyl-1 picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (475.79 +/- 6.83 and 804.31 +/- 4.52 mg Trolox equivalent/g extract, respectively) and the highest reducing Cu(2+) capacity (937.86 +/- 14.44 mg Trolox equivalent/g extract). The methanolic stem bark extract substantially depressed tyrosinase (69.84 +/- 0.35 mg kojic acid equivalent/g extract), alpha-amylase (0.77 +/- 0.01 mmol acarbose equivalent/g extract), acetylcholinesterase and butyrylcholinesterase (2.91 +/- 0.07 and 6.56 +/- 0.34 mg galantamine equivalent/g extract, respectively) enzymes. F. sur extracts were tested for anticancer properties and antiviral activity towards human herpes virus type 1 (HHV-1). Stem bark infusion and methanolic extract showed antineoplastic activity against cervical adenocarcinoma and colon cancer cell lines, whereas leaf methanolic extract exerted moderate antiviral activity towards HHV-1. This investigation yielded important scientific data on F. sur which might be used to generate innovative phytopharmaceuticals.
