Antioxidants are considered to be possible defensive agents for oxidative damage of human body. Therefore, there is a great interest in the antioxidants for supply to human as food components or as specific pharmaceutics. In this work, the amounts of Flavone C-glycosides homoorientin, orientin extracted from Black bamboo by various ultrasonic waves frequency (35, 72, 170KHz, 300Watt ±1) time (15, 30, 60min) and temperature (25℃) were compared using 50% aqueous ethanol solution. From the results, The extraction frequency 35KHz (25℃), time 30min was selected as an optimal antioxidant activity condition. |
