In order to determine the change rule of polysaccharides content in fresh rice grains at different mature stages, the polysaccharides were extracted from fresh rice grains at different mature stages by ultrasonic-microwave synergistic extraction method. The composition of polysaccharides was analyzed by HPLC, and the antioxidant activity of polysaccharides was determined by antioxidant test in vitro. The results showed that the content of polysaccharides in fresh rice was the highest at the stage of late milk, up to 46.89 mg/g. Mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, xylose, arabinose and fucose were the main components of polysaccharides at this …
