| Abstract: | Taking the dandelion as the raw materials and using microwave to study technological conditions for extraction of polysaccharide,the influence factors of dandelion polysaccharide extraction rate were studied by the single factor experiments,such as material liquid ratio,extraction times,extraction time and alcohol precipitation concentration. Used extraction rate as evaluation, the optimal extraction conditions to utilize response surface experiments was confirmed as follow：material liquid ratio 1∶17,extraction time 14 min and alcohol precipitation concentration 64%,and the dandelion polysaccharide extraction rate could reach 74.34%. |
