From: Neuroprotective and anti-oxidant effects of caffeic acid isolated from Erigeron annuus leaf
Inhibition effect of caffeic acid isolated from butanol fraction of E. annuus leaf on both ferric ion and vitamin C-induced lipid peroxidation on mouse brain homogenates (A) and free radical production determined in the presence and absence of H 2 O 2 in PC12 cell (B). Results are presented as mean ± SD of three independent experiments. (A) *P = 0.024, vs. positive control; (B) **P = 0.029, vs. positive control.
