Abstract:OBJECTIVE:To extract and determine content polysaccharides of Snakegourd root.METHODS:Using microwave technique,polysaccharides of Snakegourd root were obtained by hotwater extraction and ethanol precipitation,and content was determinated with phenol-vitriolic colorimetry.RESULTS:The polysaccharides content of Snakegourd root was 18.3012%,Recovery rate was 98.86%.CONCLUSION:The polysaccharides of Snakegourd root has been obtained for the first time by microwave technique.
Keywords:microwave technique  Snakegourd    root  polysaccharide  extraction  determination
