Figure 3

Antioxidant activities of main constituents of WEP (caffeoylquinic acid derivatives) towards production of various ROS (H 2 O 2 , O 2 ·- , HO · ) in term of fluorescence intensity. (A-C) 3,4-di-O-caffeoylquinic acid. (D-F) 3,5-di-O-caffeoylquinic acid. (G-I) 3-caffeoylqic acid (Chlorogenic acid). Integrals of ROS production were calculated from time-kinetics curves. ROS were (A, D, G) H2O2, (B, E, H) O2 ·-, (C, F, I) HO·. Data are shown as mean ± S.E.M., n = 6. *P < 0.05, **P < 0.01 vs. vehicle plus ROS. V: vehicle.
