Abstract: Ultrasonic wave was applied to extraction of polysaccharide from Rhodiola l.The effects of Ultrasonic intensity, ratio of solid and liquid, Ultrasonication time, diameter of material on extraction efficiency was studied.It was found through the orthogonal experiments that the optimum technological conditions was Ultrasonic wave intensity: 675W, time:15min, ratio of material and solove: 1:40, diameter of materal:100mu.extrcation yield was 2.63%.

Key words: Ultrasonic wave, extraction, Rhodiola l, polysccharide
