The values of Mean ± SD of triplicates.

SOD (U/mg): amount of SOD that causes 50% reduction in the extent of NBT oxidation.

Peroxidase (U/mg): change in absorbance/min at 430 nm.

GST (U/mg protein): moles of CDNB conjucated/min/mg of sample.

Polyphenol oxidase: (U/mg protein): change in absorbance/minute at 495 nm.
