Potential Antibacterial and Antioxidant Activiy of Methanolic Extract of Vigna unguiculata (L.) Walp Leaves

This study was performed to determine the bioactivity of methanolic extract of Vigna unguiculata (L.) Walp leaves as potential antibacterial and antioxidant. Based on the phytochemical screening, the methanolic extract of methanolic extract of V. unguiculata (L.) Walp leaves showed the presence of phenolic, terpenoid and saponin. The 15 wt.% of methanolic extract of V. unguiculata (L.) Walp leaves exhibited a moderate antibacterial activity against Gram positive bacterium (S. aureus) with 15.5 cm of inhibition zone diameter. But negative result was obtained against Gram negative (E. coli). The antioxidant activity of methanolic extract of V. unguiculata (L.) Walp leaves against DPPH that determined as IC50 was 66.71 mg/L.
