Abstract: Polygonatum were used as material,the effects of extraction temperature,ratio of solid to solution and extraction time on the extraction of Polygonatum water extract,polysaccharides and saponin were investigated by using single factor design and orthogonal design.The result showed that extraction temperature and ratio of solid to solution were more distinct factors than extraction time.the optimum extraction conditions by orthogonal design analysis is as follows: extraction temperature 80℃,the ratio of solid to solution 1g∶ 30mL,extraction time 3h.Under this condition,the extraction amount of Polygonatum water extract,polysaccharides and saponin were 67.92%,25.82% and 6.64%,respectively.
