| Abstract: | The technology of microwave-assisted extracting polysaccharide from pitaya flower was studied. Three main parameters, microwave power, microwave extraction time and liquid-solid ratio were tested separately, and the optimum conditions of microwave-assisted extraction were obtained by orthogonal experiment. The result shows that, the optimal method was high fire, extracting time 40s, and liquid-solid ratio 1 ： 40 （w/v）, with which the polysaccharides extraction yields of pitaya flower was （65.61±0. 10） mg · g^-1, indicating stablity and reproducibility. |
