The methanolic extract of Paeonia lactiflora roots significantly protected primary cultures of rat cortical cells exposed to oxidative stress induced by H2O2. Seven monoterpenes, paeonilactone-B (1), paeonilactone-C (2), paeoniflorigenone (3), benzoylpaeoniflorin (4), paeoniflorin (5), oxypaeoniflorin (6) and albiflorin (7), were isolated by bioactivity-guided fractionation and further separation using chromatographic techniques. Among them, compounds 2 and 4 significantly protected primary cultures of rat cortical cells against H2O2-induced neurotoxicity.
