Abstract

Objective: To evaluate in vitro antimicrobial and antioxidant activities of methanolic extract of Jasminum cuspidatum leaves extract. Method: Methanolic extract of J. cuspidatum was evaluated for its antimicrobial activity by well diffusion method and their possible antioxidant assay by DPPH scavenging activity. Result: In the DPPH scavenging activity, the IC50 value of methanol extract was 131.46 μg/mL. Further, the extract showed inhibitory activity for Grampositive and negative bacteria at different concentration. Conclusion: These results clearly indicate that J. cuspidatum is effective in scavenging free radicals and has the potential to be a powerful antioxidant. Thus, the results obtained in the present study indicate that J. cuspidatum leaves extract could be considered as a potential source of natural antioxidants and that could be used as an effective source against bacterial diseases.
