To determination of antioxidant substance homoorientin form phyllostachys bambusoides, the ultrasonic extraction and high performance liquid chromatography on-line ABTS screening method were used. Also, the various experimental variables were the frequency and time of ultrasonic system. From the results, homoorientin was high extracted at the experimental condition of low frequency 35 kHz and time 60 min. The values were +1574.71（relative area, 23.67%） and -6924.34（relative area, 1.23%）, respectively. This HPLC on-line ABTS screening method was rapid to search for antioxidants from natural products. |
