| Abstract: | Polysaccharides were extracted from chestnut using hot water extraction and ultrasound-assisted extraction.The contents of chestnut polysaccharides extracted by the two techniques were determined by anthrone-H2SO4 method after ethanol precipitation,Sevage deproteinization and organic solvent degreasing.The optimal extraction conditions were obtained by single factor and orthogonal experiments.The results showed that,the optimal conditions of hot water extraction were: chestnut 1 g,extraction temperature 60 ... |
