Blueberry leaf as materials, ethanol ultrasonic assisted extraction of blueberry polyphenols, ethanol concentration and solid-liquid ratio on blueberry ultrasonic time leaves influence the yield of polyphenols were researched, and the orthogonal experiment to optimize the ethanol ultrasonic assisted extraction technological conditions of blueberry leaf polyphenol polyphenols was used. The results showed that the optimal extraction conditions of polyphenols from blueberry leaves were as follows, 9.06% with 4min ultrasonic time, 80% ethanol concentration and 1:45 (g/mL) ratio. Ultrasonic assisted extraction is a convenient and high yield method, which is suitable for the extraction of polyphenols from blueberry leaves.
