Effect of different solvents on phytochemical composition of both date seeds. Data expressed as means ± standard deviations of three independent extractions (n = 3). TPC: Total phenolic content (mg GAE per 100 g of extract), TFC: Total flavonoid content (mg CE per 100 g of extract), CTC: Condensed tannins contents (mg CE per 100 g of extract), Different lower case letters in the same types of material indicate significant differences between the different used solvents extraction (P < 0.05). KS: Korkobbi seed, AS Arechti seed
