Evaluation of antioxidant activity of dilute acid hydrolysate of wheat straw during xylose production

► Wheat straw was used for the production of xylose and phenolic compounds. ► The production conditions of xylose and phenolic compounds were optimized. ► The yield of sugar and soluble phenolics were dependent on operational conditions. ► The optimum reaction conditions were 4.7% acid concentration, 120 °C and 45 min.
