To prepare the fruit extract, 5 g samples from each replica were homogenized with 5 mL of precooled 95% ethanol containing 3%formic acid (v/v), and after centrifugation at 10,000 × g for 15 min(4◦C), another 15 mL of 80% ethanol containing 5% formic acid (v/v)was used to extract the residue again. The supernatant was com-bined to make the final volume of 25 mL for analysis. Total phenolics content in strawberry fruit extracts was determined according tothe Folin-Ciocalteu procedure (Slinkard and Singleton, 1977). There sults were expressed as milligrams of gallic acid per gram oftissue.
