Abstract: Objective: Effects of ultrasonic wave-assisted extraction on Radix platycdonis polysaccharide were studied. The optimal extract conditions were confirmed. Methods: Effects of each factor on polysaccharide were studied through single factor test, and then the optimal ultrasonic wave-assisted extraction conditions were confirmed through orthogonal test. Results: The optimal ultrasonic wave-assisted extraction conditions are as follows: ratio of solution to materiol (V/W) 45.33~47.90, temperature 75 ℃, power 162~180 W, time 37~39 min. On these conditions the extraction rate of polysaccharide is more than 35%. Conclusion: Ultrasonic wave-assisted extraction can benefit for polysaccharide extraction.
