Effect of Clitoria ternatea flower extract (CTE) on the generation of superoxide anion as represented by the level of reduced cytochrome c a and hydroxyl radicals as represented by the level of thiobarbituric acid substances (TBARS) b in methylglyoxal (MG)/lysine-induced glycation. Each value represents the mean ± SEM (n = 3). Means with different letters are significant different (p < 0.05)
