Abstract: Rhodiola sachdlinensis from Changbai mountain was used to be material,ultrasonic wave was co-method,and extracted Rhodiola flavonoids by hot water.The condition of the sonication and flavonoids extraction of Rhodiola were studied,and the optimum technique were screened out through orthogonal test.The results showed that the size 0.125 mm,sonication time 6 s,alternat time 4 s,sonication times 7.When Rhodiola flavonoids were extracted by hot water,the extraction time 40 min,material to liquid 1:15,extraction temperature 80 ℃,extracted Rhodiola flavonoids as above,the percentage extraction of Rhodiola flavonoids was 13.02%.

Key words: Rhodiola sachdlinensis, flavonoids, ultrasonic wave, extraction
