In this work, the amounts of Flavone C-glycosides homoorientin extracted from Pseudosasa japonica leaves by various ultrasonic waves frequency (35, 72, and 170KHz, 300Watt ±2) time (15, 30, and 60min) and temperature (25℃) were compared using 50% aqueous ethanol solution. And describes analysis of the antioxidant potential of Pseudosasa japonica leaves using an high-performance liquid chromatography (HPLC) on-line ABTS+ antioxidant screening method. From the results, the highest yield of Pseudosasa japonica leaves was obtained by ultrasonic waves with a frequency of 35 KHz and an extraction time of 60min. |
