Abstract
A citrine pleurotus (Pleurotus citrinopileatus) polysaccharide and application thereof are provided, which relate to the field of natural product development and utilization. The citrine pleurotus polysaccharide includes xylose, glucose, galactose, glucuronic acid, fucose, fructose and arabinose. The citrine pleurotus polysaccharide can be applied in preparing drugs for treating sarcopenia caused by cancers. It is demonstrated that the polysaccharide of citrine pleurotus may increase a body weight and a spleen weight, restore morphology, number and density of muscle fibers, reduce inflammatory response and decrease expressions of signature proteins of Atrogin-1 and MuRF-1 for sarcopenia, and alleviate symptoms of tumor-induced sarcopenia in mice with colon cancer cachexia. New effects of polysaccharides of citrine pleurotus are discovered, which provides new ideas for exploitating the citrine pleurotus and treating the sarcopenia caused by cancers.
