Evaluation of Scavenger Properties of some Flavonoidic Vegetal Extracts Obtained from Crataegus monogyna Jacq

The scavenger properties of some flavonoidic vegetal extracts obtained from Crataegus monogyna Jacq have been studied using the chemiluminescence technique and ex vivo lipid peroxidation assay. A correlation between antioxidant activity and phenolic/flavonoidic content was observed for all the seven extracts, and a parallel behaviour with the antioxidant activity determinated by ex vivo lipid peroxidation assay and in vitro chemiluminescence tests was also noted.
