Abstract: The extraction of flavonoids from old stalk of asparagus by ultrasonic wave was studied. Experiment results showed that the optimum conditions were: 50℃,power 150W,time 45min,the ratio of material to water 1:5. On these condition the yield of flavonoids can reach 4.23%.

Key words: old stalk of asparagus, flavonoids, ultrasonic wave
