| Objective：To optimize the extraction process of polysaccharides from Qiandongnan local Dipsaci Radix,and study the antioxidantiong of polysaccharides from Dipsaci Radix.Methods The material-liquid ratio,extraction temperature, extraction time and extraction times were selected for single factor experiment. The response surface method was used to optimize the extraction process of polysaccharides from Dipsaci Radix,and the antioxidant activity of that was tested. Results The optimum extraction conditions was as follows: material-liquid ratio 1:25 (g/mL), extraction temperature 90℃,extraction time 90min, extraction times 3 times. Under these conditions, the average extraction rate of polysaccharides reaches 4.74%.In vitro experiments showed that the polysaccharides in Dipsaci Radix had good antioxidant activity.Conclusion The optimized process is simple,reasonable and feasible.The polysaccharide in Dipsaci Radix has antioxidantiong. |
