Abstract The study aimed to investigate the quantitative evaluation of phytochemicals and the antioxidant potential of leaf extract of Passiflora foetida. The antioxidant activities were analyzed the methods of DPPH, ABTS and total antioxidant activity. The leaf extract of P. foetida recorded highest total phenolic (63.91 mg/g extract), flavonoids (30.98 RE mg/g extract; 25.03 QC mg/g extract) and saponin (32.27 mg/g extract) contents antioxidant activity. The IC50 value of DPPH was (614.405 μg/mL) and ABTS was (25.18 ug/ml). P. foetida leaves also possess total antioxidant potential comparable to ascorbic acid. The antioxidant potential of extract were also correlated with total phytochemical contents, which indicates that higher phenol, flavonoids and saponin suppose to support such potential property. Therefore, the results suggest that the leaf extract of Passiflora foetida have promising therapeutic value for as natural antioxidant.
