Abstract
|
|
|
|
This study investigated the antioxidant and synergistic effects and nitrite scavenging ability of some phenolic compounds(catechin, rutin, quercetin and naringin). The electron donating abilities of naringin, quercetin, rutin and catechin were 6.7%, 92.8%, 87.6% and 92.2%, respectively. The antioxidant activities in O/W emulsion substrates were in order of rutin > quercetin > catechin > naringin. The antioxidant effect of rutin was stranger than that of BHT or a-tocopherol, a-tocopherol showed synergistic effect with catechin and quercetin, but ascorbic acid not showed effect. The nitrite scavenging abilities of catechin, quercetin, rutin and naringin were 99.0% 98.6%, 25.5% and 0.2%, respectively. The nitrite scavenging abilities of quercetin and catechin were very potent as compared with those of BHT and ascorbic acid.
