Description	Seeds of twelve white and red vine varieties cultivated on six vine-growing areas were assessed as a by-product after winemaking on the contents of total polyphenols (TP) and phosphorus (P) spectrophotometrically, total tocols (TC) by HPLC?FLD, and metals (Ca, Mg, Na, K, Fe, Zn, Cu, Mn) by FAAS. Remaining TP and TC levels were mainly affected by the variety, while levels of microelements (Cu, Mn, Zn) and P or K by the vine-growing area. The highest TC levels were found in the seeds of the Müller Thurgau, Pinot Noir and Zweigeltrebe varieties. Different white and red winemaking methods have significant impact on the TP content with higher remaining levels in white varieties. Conversely, red varieties contained higher levels of macroelements except P, however no significant differences between varieties have been found. Red varieties contained higher Fe, Cu, Zn and comparable Mn levels. Results herein revealed the considerable potential of grape seeds, a by-product of the vinification process, as a val Seeds of twelve white and red vine varieties cultivated on six vine-growing areas were assessed as a by-product after winemaking on the contents of total polyphenols (TP) and phosphorus (P) spectrophotometrically, total tocols (TC) by HPLC?FLD, and metals (Ca, Mg, Na, K, Fe, Zn, Cu, Mn) by FAAS.
