Antimicrobial and Antioxidant Potentials of Verbesina encelioides (Cav.) Benth. and Hook. Fil ex Gray

Satish C. Jain, Renu Singh and Renuka Jain    

Abstract: Methanol, cold water and hot water extracts from fresh roots of V. encelioides, a weed, were studied for their putative antimicrobial activities against select microorganisms (Bacteria: Bacillus subtilis, Enterobacter aerogenes, Escherichia coli, Pseudomonas aeruginosa and Fungi: Aspergillus niger, Candida albicans, Penicillium crysogenum, Tricophyton rubrum) by disc diffusion method at different concentrations (2.5, 5 and 10 mg disc-1) and for antioxidant potential by DPPH method. All the test extracts exhibited potential antimicrobial activity but hot water extract showed appreciable activity (IZ 23 mm) against P. aeruginosa and P. crysogenum. Hot water extract demonstrated 20.04% inhibition of DPPH at 80 µg concentration.
