Abstract: The microwave-assisted extraction the polysaccharide of Radix scrophulariae, and using phenol-sulfuric acid method to determine the polysaccharide.Investigate the influencing factors of microwave-assisted extraction by single factor test and orthogonal test,and finding out the best extraction condition,microwave temperature 50 ℃,time 6minmicrowave power 500 W,pH value 8,solid-liquid ratio 1:30 (g/mL).the yielding content of Radix scrophulariae polysaccharide was 22.44% at the optimum parameter conditions.

Key words: Radix scrophulariae, polysaccharide, microwave, phenol-sulfuric acid
