Abstract: The ultrasonic extraction method was used for extracting flavonoids in onion skin, the optimum extracting conditions were investigated. The flavonoids in onion skin were determined by sepctrophotometry. The results show that the recovery is 99.6%~105% and the coefficient of variation is 0.18%.
