The antioxidant properties of phenolic compounds were very well documented. A significant relation between phenolic content and antioxidant effect of curry leaf extract has been reported by Ningappa et al. (2008). Similarly, Kanatt et al. (2008) observed a strong antioxidant effect of mint leaf extract. They also reported that the antioxidant potential of this extract was comparable to that of the synthetic antioxidant, BHT. Recently Devatkal et al. (2010) found a positive correlation between the phenolic content of plant by-products extracts and the reduction of TBARS in cooked goat meat patties.
