Abstract
The measuring precision of pentoses or hexoses by DNS method was well, but the measuring error of mixing total sugar of pentoses and hexoses was notable. Therefore, 3, 5-Dinitrosalicyclic acid method was modified by measuring of pentoses and hexoses respectively. The result showed the recollection rates of total sugar of corncob hydrolysate were in the range of 98.90%-100.81%, the relative standard deviation was 0.62% and the precision in determination of mixing total sugar was raised obviously. So the method was accurate, fast and convenient and it was fit to determine total sugar in corncob hydrolysate in quantitation.
