摘要
为获得较多的蝴蝶花多糖,采用超声波法对蝴蝶花多糖的提取工艺进行优化。结果表明:各因素对蝴蝶花根茎多糖提取率的影响依次为料液比>提取温度>提取时间>提取功率,蝴蝶花多糖最佳提取工艺为提取时间30min,提取温度70℃,料液比1∶30。在最佳工艺条件下,超声提取蝴蝶花根茎多糖的验证性试验提取率为11.21%。进一步证实了该工艺的稳定性和可行性。
The extraction technology conditions of polysaccharides from the rhizome of I. japonica in Fanjing mountain were optimized to get the highest content of polysaccharides by ultrasonic-assisted. Results. The influencing factors of extraction ratio followed the sequence of solid-liquid ratio〉extraction temperature〉 extraction time〉 extraction power, and the optimum extracting conditions included extraction time 30 min, extraction temperature 70℃ and solid-liquid ratio 1：30. Under these conditions, The rate of polysaccharides extracted reached 11.21%, indicating that this process is efficient and stable.
