The scavenging activity of flavonoids decreases in the order: myricetin > quercetin > rhamnetin > morin > diosmetin > naringenin > apigenin > catechin >5,7- dihydroxy -3′,4′,5′-trimethoxyflavone > robinin > kaempferol > flavone. The activity increases with the number of hydroxyl groups...
We now show that methyl-esterified dimers and trimers of 3-hydroxybutyrate (ME-3HB), produced by bacteria capable of polyhydroxybutyrate biosynthesis, have 3-fold greater hydroxyl radical–scavenging activity than glutathione and 11-fold higher activity than vitamin C or the monomer 3-hydroxybutyric ...
摘要: The role of β- N-oxalyl- l-α, β-diaminopropionic acid, a non-protein amino acid, as an effective hydroxyl radical scavenger is identified by in vivo and in vitro experiments.关键词: Lathyrus sativus Leguminosae Legume Grass pea β- N-Oxalyl- l-α, β-diaminopropionic acid ...
Five experiments common to all three models yielding greater than 0.5g of MRPs were assessed for antioxidant activity. All MRPs exhibited detectable, but variable, non site-specific hydroxyl radical (·OH) scavenging activity (30–90%) in the deoxyribose assay. MRPs derived from a ribose-...
Their activity as hydroxyl radical (OH) scavengers is reported here by using three different methods: deoxyribose degradation, hydroxylation of benzoate and hydroxylation of 2′-deoxyguanosine to give 8-hydroxy-2′-deoxyguanosine (8-OHdG) as assessed by RP-HPLC (MS). Fenton reactions (Fe2+/Fe3...

The IC50 value for methanol and aqueous extract in deoxyribose method were determined 0.76 and 0.99 mg/ml.Conclusion: Methanol and aqueous extracts exhibited hydroxyl radical scavenging activity. However, methanol extracts showed better results, but total phenolic content of aqueous extract was greater....
