<p>An enzyme-assisted aqueous extraction process for polyphenols and flavonoids from persimmon (Diospyros kaki Thunb.) leaves was optimized using Response Surface Methodology. The optimal pretreatment conditions were 0.05% (w/w) Viscozyme L, 39°C, and 2 h 48 min, followed by extraction at pH 10.2, 94°C, for 30 min. Under these conditions, the extract contained 2.75 g GAE/100 g dry weight of total polyphenols and 2.99 g QE/100 g dry weight of total flavonoids. The experimental values were consist...</p>
