摘要： 研究了循环超声强化提取肉苁蓉中多糖和甜菜碱的工艺条件. 实验结果表明，将肉苁蓉粉碎至40目，液固比为60 ml/g时提取较为适宜. 循环超声提取多糖和甜菜碱的较优工艺条件是：提取温度40℃，超声功率1000 W，提取时间10 min，在此条件下，多糖的提取量为46.9 mg/g，甜菜碱的提取量为136.5 mg/g，分别相当于沸水回流7 h时提取量的107.3%和103.8%.

Abstract: The circulating extraction of polysaccharides and betaine from Cistanche deserticola enhanced with ultrasonic wave were investigated. C. deserticola was comminuted to the size of 40 meshes and extracted with ultrasonic wave power of 1000 W in water at 40oC for 10 min. Under the above optimal conditions, the extracted amount of polysaccharides was 46.9 mg/g and that of betaine was 136.5 mg/g, which corresponded to 107.3% and 103.8% of those extracted with reflux in boiling water for 7 h.
