Black tea which contains polyphenol is important for health benefits and it is considered as antioxidant contents . The extraction parameters, time and temperature and kind of solvent extraction, can Influence the polyphenol concentrations of Black tea, and were investigated in this study. The purpose of the study was to quantify the polyphenols (catechin, epicatechin, epigallocatechin, epicatechin gallate, epigallocatechin gallate) in different kinds of teas ( Lipton , Alrabee , Layalina ) which are available in Syria market.The study was conducted using two types of solvents methanol 70% the adoption of the reference method adopted ISO14502-1 and water 100% , at different extraction times (1, 3, 5, and 10 minutes) and extraction temperatures (60°C , 70 °C , 80°C, 90°C, 100°C). the total polyphenols content was determined using the phenol reagent (Folin Ciocalteu reagent) adoption gallic acid as standard compound the overall content values of polyphenols have been monitoring in extracts methanol 70% and water 100% .
