Antioxidant and Antibacterial Activity of Field Grown and Tissue Cultured Root Callus of Mangrove Species

Abstract

Aim: The main aim of this study is to evaluate the anti-oxidant and antimicrobial activity of mangrove species and the development of the callus biomass. Study Design: This is the first comparative evaluation report of field grown root and tissue cultured root callus of mangrove on anti-oxidant and anti-bacterial activity. Acanthus ilicifolius, Calophyllum inophyllum and Excoecaria agallocha were tested in this present investigation. Place and Duration of Study: Centre of Advanced Study in Marine Biology, Faculty of Marine Sciences, Annamalai University, Parangipettai 608 502, Tamil Nadu, India. Between February 2012 and July 2013 Methodology:  In order to develop callus biomass, a number of growth hormones were supplemented with the MS medium. Following the callus development, anti-oxidant and anti-microbial activities were tested with field grown root and its tissue cultured root callus of Acanthus ilicifolius, Calophyllum inophyllum and Excoecaria agallocha. This was confirmed by different anti-oxidant, anti-bacterial and minimum inhibitory concentration assays. Results: Maximum (89%) root callus biomass was obtained from Acanthus ilicifolius on MS medium fortified with 0.3+0.3 mg/L of 2,4-D and KIN. 2,4-D 0.3mg/L and BAP 0.5 mg/L showed the maximum callus from both Calophyllum inophyllum (81%), Excoecaria agallocha (58%). In addition anti-oxidant and anti-bacterial effect of root and root callus of these three species were tested. In this study the root callus materials of all the three species showed the best anti-oxidant anti-bacterial activities. Conclusion: The metabolites from mangroves are good remedy for number of health problems especially the enhanced level of metabolites through the tissue culture techniques. The present study confirmed the anti-oxidant and anti-bacterial effect of Acanthus ilicifolius, Calophyllum inophyllum, Excoecaria agallocha n root extract.   This study will be a key to develop a new drug to achieve healthy life. especially the root callus materials showed the better activity when compared to the field grown plants.
