Fig. (2) Comparison of the protective effect of the antioxidant compounds on PQ-induced mortality. Flies fed with effective concentration (0.02%) of different antioxidants (4-Hydroxyisophthalic acidDHA-I, Nicotinamide-NA, Ellagic Acid-EA, Quercetin-Que) were subjected to PQ (20mM) treatment and mortality was recorded after 24 of exposure. Values are mean±S.E. (n=6; 10 flies per replicate) and bars denoted by identical lowercase alphabets (a–c) indicate no significant difference, whereas, values denoted by different alphabets indicate a statistically significant difference (p<0.05).
