In this experiment, it was suggested that the highest contents of total and free phenol was obtained by the highest dose of Zn (1%) in combination with 0% B, and single dose of Zn (0.5%) in combination with 0% B respectively. The superoxide dismutase (SOD) activity was found to increase with respect to control following the highest dose of B (0.5%) alone. However, the peroxidase (POD) activity increased more with respect to control following the single dose of B (0.25%) rather than the double dose (0.5%). The highest Molybdate reducing antioxidant potential (MRAP) was observed in 0.5% Zn in combination with 0% B, whereas that of 2, 2-Diphenyl-β-picrylhydrazyl radical scavenging activity (DPPHRAC) was found in the interaction effect of the double doses of both Zn (1%) and B (0.5%), which also offered the lowest lipid peroxidation. The highest pyruvic acid development was observed by the interaction effect of 0% Zn and 0.25% B. Based on the average values of the biochemical parameters and the results of PCA, the treatment with Zn<sub>1</sub>B<sub>3</sub> (0% of Zn in combination with double dose of 0.5% of B) was proved to be most promising with respect to antioxidant properties.</p>}, number={3}, journal={Notulae Scientia Biologicae}, author={DENRE, Manas and BHATTACHARYA, Amitava and PAL, Srikumar and CHAKRAVARTY, Arunabha and CHATTOPADHYAY, Arup and MAZUMDAR, Debasis}, year={2016}, month={Sep.}, pages={373–379} }
