Technology of Ultrasonic-assisted Extraction of Polyphenols from Artocarpusheterophyllus Seeds

    Graphical Abstract
    • Abstract
  • Experiments were conducted on technology of ultrasonic-assisted extraction of polyphenols fromArtocarpusheterophyllusseeds with different ultrasonic temperature, ultrasonic time, ultrasonic power, ethanol concentration and solid-liquid ratio.Single factor and orthogonaltest on 5 factors above-mentioned demonstrated that effect of factors was ordered by ethanol concentration > ultrasonic temperature > material to liquid ratio > ultrasonic time > ultrasonic power.Experiments indicated that the optimal extraction technology was under 45℃ ultrasonic temperature,10 min ultrasonic time,55 W ultrasonic power,1:50 solid-liquid ratio, and 65% ethanol concentration.The yield extracted from A.heterophyllus seeds was 5.368 mg/g.
