The present study was aimed to characterize the enzymatic and non-enzymatic antioxidants in in vitro grown adventitious roots of Withania somnifera (genotype Jawahar 20) under PEG induced drought. Due to the illimitable therapeutic values of roots and the fact that “enhanced activity of antioxidants is directly correlated with oxidative injury promoted by drought”, five major antioxidants (phenol, flavonoids, SOD, CAT and ascorbate) were evaluated. The roots of Withania somnifera were not able to enhance enzymatic antioxidants like SOD and CAT infact 19.28 to 28.54% and 63.89 to 89.48% reduction in SOD and CAT activity were measured with increasing stress duration. In contrast roots were efficient to enhance the phenols and flav... view more»
