摘　　要：采用超声辅助水提醇沉法提取葫芦巴中多糖,考察提取时间、乙醇体积、乙醇浓度、料液比对多糖提取率的影响。结果表明,最佳提取工艺参数为:料液比1∶40 g/m L,乙醇浓度90%,乙醇体积倍数40,超声提取时间1.5 h。在最佳提取条件下,葫芦巴多糖提取率1.34 mg/g,多糖纯度达67%。Using ultrasonic-assisted water extract alcohol precipitation method to extract the polysaccharides from Trigonella foenum-graecum L. The influence of extraction time,ethanol volume,ethanol concentration and the ratio of solid to liquid on the polysaccharides extraction yield was investigated. The results showed that the optimum conditions for extracting the polysaccharides of Trigonella foenum-graecum L.were as follows： 90% ethanol,1∶ 40 g/m L,1. 5 h and 40 times for extraction solvent,the ratio of solid to liquid,extraction time and ethanol dosage,respectively. Under the best extraction conditions,the extraction rate for Trigonella foenum-graecum L. polysaccharides is 1. 34 mg/g,with up to 67% polysaccharides content in the crude polysaccharide.
