Optimize the impact of extraction of the major factors by orthogonal experiments, included extraction temperature, extraction time, ethanol concentration and the ratio of solid to liquid.
通过正交试验，对影响提取效果的主要因素包括提取温度、提取时间、乙醇浓度和固液比进行优化。
The results showed that extraction temperature and solid-liquid ratio had a significant impact on the extraction yield of polysaccharides, but extraction time was not significant.
结果显示，提取温度和料液比对多糖提取率有显著性影响，提取时间对多糖提取率无显著性影响。
