Effect of curcumin on GSH concentration (A and B), SOD (C and D) and CAT (E and F) activity in D-gal and NA mice group. The GSH, SOD, CAT was detected by using bioassay technique among Vehicle, Cur-Con, D-gal, Curcumin + D-gal, Ast + D-gal, NA, Curcumin + NA, Ast + NA groups. GSH level, SOD and CAT activity were expressed in μmol/mg, U/30s, and μmol/min/mg, respectively. Data was presented as mean ± SEM, n = 8 each group; *p < 0.05, **p < 0.01 ***p < 0.001, ****p < 0.0001 ns = not significant.
