影响南瓜多糖提取率的因素有：料液比、浸提时间、温度、提取次数。
The factors that affected the extraction of pumpkin polysaccharide included the ratio of material to solvent, extracting time, temperature and times of extracting.
在此条件下的刺梨多糖提取率可达2.18%，与模型预测值非常接近。
Under these optimized conditions, the extraction yield of polysaccharide was 2.18%, exhibiting a good agreement with the predicted value.
结果发现：影响多糖提取率最主要的因素是料液比，其次是提取温度和时间。
The results exhibited that solid-liquid ratio is most important factor for the extraction percentage of the polysaccharides, the time and temperature are the second.
