| Abstract | ||
| The current study included the extraction of total phenols, tannins and proanthocyanidins from grape (Vitis vinifera) and date (Phoenix dactylifera) seeds using different extraction conditions. The temperatures (25 and 30)Cᵒ were the best degree in extraction of total phenols ,tannins and proanthocyanidins from date and grape seeds, respectively. While extraction time12 hours and shaking speed (50) rpm were the best in extraction the studied compounds from both extracts,except the best extraction of tannins from grape seeds was at 100 rpm ,and 6 hrs were best for extraction tannins and phenols from grape seeds. Acetone was chosed as the best solvent than others which used in the study in extraction total phenols ,tannins and proanthocyanidins from grape and date seeds . Acetone 70% was found to be the best when determined the best concentration of solvent in extraction the studied compounds from both extracts. | ||
