Abstract:In order to study the differences in nutrients and active ingredients of the fruit bodies of four strains of Hypsizygus marmoreus，such as white Hypsizygus marmoreus，Cuixiangu，Xieweigu and Haixiangu，it provided a reference for the development and utilization of the true mushroom. The content of nutrients and active ingredients was determined by national food standards and conventional methods.Crude fat，total sugar，niacin，vitamin B6，vitamin B12，vitamin E，polysaccharide，saponin and choline were the highest in white Hypsizygus marmoreus；Crude fiber，vitamin A，vitamin B2，vitamin C and flavonoids were the highest in Cuixiangu；crude protein and phenolic acid were the highest in Xieweigu，vitamin B1 was the highest in Haixiangu；Al，As，Cr and Cu were in white Hypsizygus marmoreus.The content of Cd and Ni was the highest in Cuixiangu，K and Mn were the highest in Xieweigu，and Zn was the highest in Haixiangu.Co，Hg，Pb，Pd，and Se components were not detected. It appeared that the content of active ingredients and nutrients in the white mushroom is high.
