Abstract
Stilbenes are secondary metabolites in Vitis vinifera. The increasing evidence of health benefits of trans-resveratrol in the last two decades has triggered the interest in studying the levels of this and other stilbenes in grapes, wine and winemaking residues. In Chile, more than 100.000 tons of winemaking residues are produced each year, including pomace, seeds, stalks and canes. In this research, profiles and levels of stilbenes in these waste products are comparatively studied. Then, a stilbene rich extract was produced at bench scale using canes, the crude extract was characterized by HPLC-DAD-ESI-MS/MS and biological assays.
