Oxygen active species-scavenger properties of coumarins

Phytotherapy Research 10(Supplement 1): S75-S78
Oxygen active species-scavenger properties of coumarins
The activities of 19 plant-derived or synthesized coumarins as scavengers of free radicals were examined. Coumarins with an ortho-dihydroxy function lowered the concentration of superoxide radicals. Hydroxyl radical production was inhibited significantly by 4-hydroxycoumarin, fraxetin and 4-methyldaphnetin. Ortho-dihydroxylated coumarins inhibited lipid peroxidation to a similar extent as the reference compound.
