ABSTRACT
Reactive oxygen species [ROS] cause oxidative damage to the tissues and protection from such damages are provided by
endogenous and exogenous antioxidants. Plant based antioxidants are preferred due to the multiple mechanisms of actions
and of the phytochemicals present in them. 80% alcoholic extract of leaves of Aloe vera, Bacopa monniera, Moringa
oleifera and rhizome of Zingiber officinale was tested individually and in combination in equal proportion of each extract
for DPPH scavenging activity and reducing power. The results indicate that the combination of the extract has better DPPH
scavenging action and reducing power compared to the individual plant extract indicating synergistic and supra additive
effect of phytochemicals present in the extract.
