摘要: UNLABELLED Essential oils have been studied for their unique ability to act as antioxidants. Antioxidant activities of 423 essential 48 different botanical families were evaluated antioxidant free radical scavenging agents using the 1,1-diphenyl-2-picrylhydrazyl method. Seventy-three showed 50% or more inhibition at a concentration 1.25 mg/mL. The 73 most active oil samples further series dilutions estimate EC(50) . ranged from 4 2000 μg/mL. Oils having an less than 300 μg/mL (20 selected samples) subjected β-carotene bleaching activity test and detailed analysis including thin layer chromatography, gas chromatography/mass spectrometry, high performance liquid chromatography bioautography. Lamiaceae Myrtaceae effective Thymol carvacrol major constituents in family eugenol was terpene all Myrtaceae. PRACTICAL APPLICATIONS Supplementation food with spices containing may counteract retard process oxidative damage, lipid oxidation elevate final product.
