| Abstract: | The paper investgates the effect of extracting temperature, extracting time,and material-medium-rade on extraction of polysaccharides from stem of sweet potato with orthogonal design. The combination of adding 40 times of water, at the temperature of 100℃ and with etracting time of 25 minute is recommended. By means of decompressor concentration,ethanol precipitation, dialysing and drying, the final extractant from stem of sweetpotato is identified as polysaccharide. |
