Background: Wine polyphenols have antioxidant properties. Different polyphenols have various biological activities on atherogenesis and carcinogenesis.
Material and methods: The composition on 5 polyphenols of 16 wines of Castilla (Spain) is determined by HPLC.
Results: Polyphenols concentrations varied largely among the different wines. Most red wines had higher amounts of polyphenols than white wines.
Conclusions: The diverse composition on polyphenols of each wine allows to suggest different biological effects.
