In the present article, ultrasound-assisted extraction (UAE) of polysaccharides from Angelica sinensis were investigated. The aim of the study is to examine the extraction parameters such as ultrasound power (140–180W), the ratio of liquid to solid (5–7), extraction time (40–50min) and extraction temperature (80–100°C) and to obtain the best possible combinations of these parameters through response surface methodology (RSM). Based on contour plots and variance analysis, optimum operational conditions for maximizing polysaccharides yield were found to be 180w, 7, 45min and 90°C. Under the optimum operating conditions determined, 6.96% polysaccharides were achieved. In addition, the results showed that A. sinensis polysaccharides (ASP) could increase antioxidant enzymes activities and decrease the MDA levels in the skeletal muscle of exhaustive exercise rats. This study provides strong evidence that A. sinensis polysaccharides supplementation possessed protective effects against exhaustive exercise-induced oxidative stress.
