Analysis of Nutrient Components and Bioactive Substance of Hypsizygus marmoreus and Study on Activity of Polysaccharides Scavenging Free Radicals

In this research, mensurated the main nutrition ingredients, amino acids, bioactive substancer contents from Hypsizygus marmoreus, and studied the polysaccharides scavenging free radicals activity. The results showed that, the nutritional contents of Hypsizygus marmoreus are rich and comprehensive, the crude protein, crude fiber and mineral are high, but the crude fat content is lower, the bioactive substancer suah as choline and VC are rich. The polysaccharides of Hypsizygus marmoreus have an evident effect on scavenging O2· and ·OH.
