摘　　要：目的:考察超声波提取技术在薯蓣皂苷元提取中的应用,并寻求一种高效节能的薯蓣皂苷元提取方法。方法:采取先溶剂提取再酸水解的方法提取黄姜中的薯蓣皂苷元,对提取环节进行了五种不同方法优化组合和对比研究,以及反应机理的探讨,并与传统的直接酸水解法进行了比较分析。结果:对黄姜磨浆后进行超声提取的方法提取效率最好,收率比传统提取法提高15,用酸量降低90以上,提取物纯度高。结论:对黄姜磨浆预处理后进行超声提取能充分发挥超声波的作用,该方法具有收率高,节约能耗、减少环境污染的特点。AIM： To study the application of ultrasonic extraction in process of extracting diosgenin from Dioscorea zingiberensis C.H. Wright, and to evaluate its merits. METHODS： A new process of ethanol extracting and hydrochloric acid hydrolysis was provided to extraction diosgenin, and five different extraction methods were studied and compared, and the reaction mechanism was discussed. RESULTS： The ultrasonic extraction method was more efficient. Compared with the traditional water-hydrolylis, extraction rate was 15 percent higher, dosage of hydrochloric acid was registered 90 percent decrease, and the production was purer. CONCLUSION： The grinding pretreatment of Dioscorea zingiberensis is help to enhance the effects of ultrasonic extraction, the method has some advantages in efficiency, energy-saving and low pollution.
