Effects of Curcumin on longevity and selected biochemical parameters in D. melanogaster. Longevity (A), Total thiols (B), Glutathione S-transferase activity (C), Nitric oxide level (D), Hydrogen peroxide level (E), Catalase activity (F), and Acetylcholinesterase activity (G). in D. melanogaster after exposure to Curcumin (0.2, 0.5, and 1 mg/kg diet) for 7 days. Data are presented as Mean ± SEM of 30 flies/vial with 5 replicates per treatment group. Significant differences from the control group are indicated by *(p < 0.05). In (A), the p values (log – rank tests) for each group include: Ctrl versus 0.2 mg/kg diet (p = 0.4706), 0.5 mg/kg diet (p = 0.5567), 1 mg/kg diet (p = 0.3767). The maximum lifespan in each group represents the percentage of surviving flies.
