Other claims from this paper (9)
- Intervention effect Persimmon fruit extracts inhibited oxidative degradation of 2-deoxyribose (2-DR) in a dose-dependent manner.
- Observation Inhibition of 2-DR degradation varied considerably among individual persimmon fruits.
- Association Protection of 2-DR degradation was higher in the Fe(III)-citrate/ascorbate system than in the Fe(III)-EDTA/ascorbate system.
- Mechanism Antioxidant protection of persimmon extracts comes mainly from free radical scavenging rather than metal chelation.
- Intervention effect Persimmon extracts prevented iron-mediated lipid peroxidation in rat liver homogenates.
- Association Prevention of lipid peroxidation by persimmon extracts correlated significantly with inhibition of 2-DR oxidation.
- Association Sugar content of individual persimmon fruits correlated inversely with inhibition of 2-DR degradation.
- Mechanism Maturation may decrease soluble antioxidant concentration or efficiency in persimmon fruit.
- Observation Extracts from commercial persimmon fruits showed mainly radical-scavenger activity and relevant antioxidant activity.
