Abstract: The optimized extraction conditions of polysaccharides from burdock with double-enzymes by orthogonal test are as follows: respective quantity of papain and plant hydrolytic proteinase 2%, temperature 45℃, respective reaction time of the double enzymes 4 h, pH 8.0 and ratio of solid-liguid 1:15. Under the conditions, the extraction rate of burdock pohysaccharides is 12.40%.
