摘要: Several monofloral Cuban honeys were analyzed to determine their free radical-scavenging activity and from this the total antioxidant content was estimated. The protective effect against lipid peroxidation in an vitro model of rat liver homogenates evaluated and, lastly, mineral honeys, which can be related maintenance intracellular oxidative balance, determined. scavenging capacities hydroxyl superoxide radicals determined using spin-trapping technique hypoxanthine/xanthine oxidase assay, respectively. Lipid through production TBARS hydroperoxides. All tested showed potential with Linen vine displaying highest capacity towards DPPH, radicals, while least efficient Christmas honey. Honeys also inhibited, a concentration-dependent mode, homogenates, resulting best effective ability scavenge protect may contribute certain help preventing/reducing some inflammatory diseases stress is involved. A eight minerals identified quantified as follows: cadmium, chromium, copper, nickel, iron, manganese, lead, zinc. Minerals found higher concentrations zinc manganese.
