Red and white wine polyphenols have been reported to provide substantial health benefits. In this study, the cytotoxic activity of red and white wine polyphenolic extracts and of resveratrol was evaluated against different cancer cell lines-human cervix adenocarcinoma HeLa, human breast adenocarcinoma MDA-MB-361, and human breast carcinoma MDA-MB-453 and normal human peripheral blood mononuclear cells (PBMCs). Qualitative and quantitative compositions of wine polyphenolic extracts obtained by fractional vacuum distillation of corresponding wines were determined using spectrophotometric methods and high-performance liquid chromatography with diode array detection and liquid chromatography with electrospray ionization-time of flight mass spectrometry analysis. It was demonstrated that wine polyphenolic extracts and resveratrol exerted higher cytotoxic activity against HeLa and MDA-MB-453 cells in comparison to MDA-MB-361 cells and unstimulated and stimulated PBMCs. Furthermore, white win...e polyphenolic extract exhibited a significantly higher antiproliferative action on cancer cell lines than red wine extract. The presence of condensed or fragmented nuclei in HeLa cells, pretreated with extract of white wine and stained with a mixture of acridine orange and ethidium bromide, pointed to the morphological signs of apoptosis. In addition, HeLa cells in late stages of apoptosis or secondary necrosis were also observed. Results from our study suggest that polyphenolic extracts from red and white wine may have anticarcinogenic potential.
