In the present investigation the oxidative stress experienced by Ficus bengalensis growing in adverse habitat (AH) in terms of reactive oxygen species (ROS) i.e. hydrogen peroxide (H 2 O 2) ; antioxidant status of superoxide dismutase (SOD); iron chelation activity; free radical scavenging activity and lipid damage, are examined and compared with that of normal habitat (NH) plants. The biochemical assays were performed for both leaves and stem samples. The results shows that H 2 O 2 and SOD

In case of free radical scavenging activity 30% increase was shown by leaves samples of AH while 19% increase was seen in the stem samples. The Lipid damage was 13% higher in leaves sample of AH and 8% increase was seen in case of stem samples.
