Abstract: Medicinal value of Adiantum lunulatum due to the presence of the phytochemicals and this phytochemicals have major role in the antioxidant and antibacterial activity. DPPH assay and antibacterial activity analysis help to identify the medicinal potential of this fern. Agar well diffusion method and minimum inhibitory concentration analysis (0.2 mg/ml, 0.4 mg/ml, 0.6 mg/ml, 0.8 mg/ml and 1 mg/ml) carried out against bacterial strains such as Staphylococcus aureus, Klebsiella pneumonia, Proteus vulgaris and Escherichia coli. DPPH assay help to identify the free radical scavenging activity of plant extract. The result indicates that increase concentration of extract has direct influence corresponding to the percentage of free radical scavenging activity. Bactericidal activity analysis shows more bacterial growth inhibition at 0.8 mg/ml and 1 mg/ml against most of bacterial strains. Adiantum lunulatum show increased effectiveness against various diseases and need further research study.
