Nineteen major polyphenolic phytochemicals including hydroxycinnamate derivatives, flavanols, flavonols, and anthocyanins, were determined in 40 experimental red wines employing HPLC-DAD. All wines analysed were young (non-aged), produced, and stored under identical conditions, in an effort to minimize the effect of oak wood and vinification technology. The data obtained from this examination composed...
Ethyl acetate extracts of seeds originating from nine Hellenic native and international Vitis vinifera varieties cultivated in Greece were screened for their contents of characteristic polyphenols. The compounds determined were principal constituents of low molecular weight, including gallic acid (GA), catechin (CT), epicatechin (ECT), epigallocatechin (EGC), epicatechin gallate (ECG), epigallocatechin...
Twenty-six white wines of ''Appellation of Origin of High Quality'', covering all viticultural areas of Greece were assayed for their polyphenolic content, using high-performance liquid chromatography coupled with diode array detector. Further, the antiradical activity and reducing power of the wines were evaluated. In both cases, the antioxidant potency of the wines was correlated with the total...
