To main objective of the present study was to investigate the antibacterial and antioxidant property of Cocus nucifera crude shell extract. The antibacterial activity of Cocus nucifera aqueous crude shell extract was determined by agar well diffusion assay against 5 pathogenic bacteria at 5mg/ml concentration namely Bacillus cereus MTCC No: 6840 (21mm), Staphylococcus aureus MTCC No: 7405 (15mm), Pseudomonas aeruginosa MTCC No: 4676 (15mm), Escherichia coli MTCC No: 1588 (16mm) and Salmonella typhi MTCC No: 1167 (18mm) Furthermore the capacity to scavenge free radicals was assessed by DPPH assay with 100% inhibition at 1mg/ml concentration. The chemical constitutes of the crude shell extract were further authenticated by GC-MS analysis. These findings demonstrate that the shell extracts of Cocus nucifera present excellent bioactive properties with beneficial virtues.
