摘　　要：以大蕉皮为原料,粗多糖的提取率为指标,采用溶剂提取法和超声波辅助提取法对粗多糖的提取工艺进行研究。结果表明,溶剂提取法的最佳工艺条件为:料液比1:25、水浴温度85℃、水浴时间60 min、提取次数3次,粗多糖的提取率为4.892%;超声波辅助提取法的最佳工艺条件为:料液比1:40、超声时间30 min、水浴时间45 min、提取次数3次,粗多糖的提取率为17.064%。比较2种方法,超声波辅助提取法的粗多糖提取率远远高于溶剂提取法。与香牙蕉相比,大蕉皮中粗多糖的含量明显高于香牙蕉中粗多糖的含量。In this study, the conditions of extracting raw polysaccharides from plantain peel by solvent extraction method and ultrasound-assisted extraction method were optimized respectively. The results showed that the optimum conditions for solvent extraction method are ratio of solution to solid 1：25, and temperature 85 ℃ for 3 times, 60 min each time, and for ultrasound-assisted extraction method are ratio of solution to solid 1：40, extracting at 85 ℃ for 3 times, 45 min each time with ultrasonic treatment. The yield of raw polysaccharides extracting by solvent extraction method and ultrasound-assisted extraction method are 4.892%, 17.064% respectively. So ultrasound-assisted extraction is more suitable than solvent extraction on extracting raw polysaccharides from plantain peel. Compared with banana peel, plantain peel contains higher level raw polysaccharides.
