摘　　要：通过单因素料液比、提取温度、提取时间和提取次数对提取率的影响和正交实验设计方法对绞股蓝多糖水提醇沉法的工艺进行了优化及绞股蓝多糖咀嚼片研制。实验结果表明,水提醇沉法提取多糖最佳工艺条件为料液比1:16,100℃提取2次,每次1 h。绞股蓝多糖咀嚼片最佳配方为绞股蓝多糖粉20.00%、淀粉9.75%、蔗糖粉40.00%、奶粉12.30%、甘露醇14.95%、柠檬酸0.50%。The extraction of polysaccharides from Gynostemmapentaphyllum Makino was studied and the formula of the chewable tablet with the extracted polysaccharide as raw material was also studied in this paper. During the extracting process, four main factors including ratio of solid to liquid, extracting temperature, extracting time and degree were studied by single factor analysis method and the optimal processing conditions for water extraction and alcohol precipitation were obtained by orthogonal experiments as follow： ratio of solid to liquid 1：16, extracting temperature 100℃, extracting times 2 and extracting time lh. The best formula of the chewable tablet was follows： Gynostemma pentaphyllum Polysaccharides powder 20%, starch 9.75%, sugar 40%, milk powder 12.30%, mannitol usp 14.95% and citric acid 0.5%.
