Table 4 Normalized ROS levels and difference in ROS levels normalized to day 0, the untreated condition or WT of CLS assay at day 0, 7, 13, and 17 for the ∆sir2 and ∆tor1 strains. Data used in comparison were significant at p < 0.001. Q, PCA and HD referred to quercetin, protocathechuic acid and Hom Dang, respectively. Negative values indicated the decreased values.
