| Abstract: | The study was to determine the optimum extraction process of total flavonoids in polygonum aviculare with ultrasonic wave through orthogonal test. The effects of ethanol concentration, material-liquid ratio, ultrasonic temperature and ultrasonic time on extraction rate of total flavonoids were investigated. The results show that the optimum extraction conditions of total flavonoids are material-liquid ratio of 1 ： 25, ultrasonic temperature of 45 ℃, ultrasonic time of 25 min with 90% ethanol as the extraction solvent. Under these conditions the flavonoids extracted from polygonum aviculare could reach 12. 012 mg/g. |
