STUDY OF TOTAL PHENOLICS, TOTAL TANNINS ANTIOXIDANT POTENTIAL AND ANTIMICROBIAL ACTIVITY OF AILANTHUS EXCELSA LAbstract
Ailanthus excelsa leaves were evaluated for antimicrobial activity against clinical isolates obtained from patients with eye and skin infections and also for its antioxidant potential. The bacterial isolates obtained were identified to be S. aureus, P. aeruginosa, E. coli and the fungal isolates were identified as Aspergillus niger and Penicillium. The extract showed a maximum zone of inhibition against A. niger followed by P. aeruginosa. But it did not exhibit any inhibitory activity against S. aureus. There was a remarkable inhibitory activity recorded against E. coli and Penicillium. The extracts were found to possess 0.7954 µg/g of total Tannins and 1.41µg/g of total Phenols. The extract also exhibited 12.5% radical scavenging activity in FRAP assay and 8.5% activity in CUPRAC assay.
