| Abstract: | It was found that the first derivative spectrometric value of polysaccharide phenol sulfuric acid reaction system was proportional to the content of polysaccharides A phenol sulfuric acid derivative spectrometry for determination of polysaccharides in edible fungus was proposed and proved to be an easy,rapid and accurate method with good selectivity, sensitivity and little interference of sample matrix color The method was used to determine the content of polysaccharides in Grifola frondosa, Hericium, Agaricus Blazie with satisfied results |
