摘要: Abstract The objectives of this study were to the antioxidant activity and free radical-scavenging effects extracts from guava leaves dried fruit. results indicated that 94.4–96.2% linoleic acid oxidation was inhibited by addition leaf tea at a concentration 100 μg/ml. fruit exhibited weaker than did extracts. also demonstrated scavenging on ABTS + radicals superoxide anion increased with increasing concentrations. displayed significant ability peroxyl radicals. However, decreased when extract greater 10 μg/ml. various cultivars more commercial chromatogram data contained phenolic acids, such as ferulic acid, which appeared be responsible for their activity. Correlation analysis there linear relationship between potency, content compounds
