Abstract:This study aimed to optimize the ultrasonic treatment parameters for total flavonoids extracted from lotus power by single factor tests and response surface methodology. Effects of liquid-solid ratios, ethanol con- centration, ultrasonic treatment temperature and time on extraction yield of total flavonoids were studied. Re- sults showed that the optimum ultrasonic assisted extraction parameters were liquid-solid ratios of 18.5(mL/g), ethanol concentration of 82 %, ultrasonic treatment temperature of 74 ℃, extraction time of 53 min under ultra- sonic power 250 W. Extraction yield of total flavonoids achieved 1.658 2 % under the optimum parameters.
