The value of the ratio K a /K c indicates the relative capacity (antioxidant capacity) of red wine to interact with peroxyl radicals. V 0 is the rate of the reaction of the crocin with the peroxyl radical and can be calculated with the following formula: V 0 = Δ [Absorbance 443 (t = 2 min)-Absorbance 443 (t = 12 min)] for crocin in the absence

Purpose of this study is to analyse the antioxidant capacity (measured by means of the crocin bleaching method) of several samples of Sicilian red wines and to evaluate their dependency on the vintage and on the grape variety. Finally, the correlation between the single flavonoids compounds and the antioxidant capacity has been investigated.

Relationship among antioxidant activity, vasodilation

The relationship among antioxidant activity, based on the electron-spin resonance determination of the reduction of Fremy's radical, vasodilation activity, and phenolic content was investigated in 16 red wines. The wines were selected to provide a range of origins, grape varieties, and vinification methods.

Significant and positive correlations were found between antioxidant capacity and total polyphenol content, especially in the Jurkat cell oxidation assay (r: 0.96, p < 0.01). Results suggest that these dietary components could be a source of antioxidants that protect from oxidative stress.

Effects of Fining Agents on Antioxidant Capacity of Red Wines

Key words: antioxidant capacity, fining, phenolics, red wine. INTRODUCTION Antioxidant activity is a fundamental property impor-tant for life. Many of the biological functions, such as anti-mutagenicity, anti-carcinogenicity and anti-aging, originate from this property1,8. Among beverages, red wines have been reported to be more protective than
