Abstract: | The effect of material granularity, extraction times, extraction time, mi-crowave power and solid-liquid ratio on the yield of polysaccharide of Dendrobium huoshanense in microwave-assisted extraction was discussed through single factor experiment. The key factors in polysaccharide extraction and the advantages over the traditional extraction method were studied based on orthogonal experiment. The results showed that the influences became unobvious with the promotion of the fac-tor’s level. The orthogonal experiment showed that the optimal factor in the mi-crowave-assisted extraction was that the sample was extracted for four times with an extraction time of 40 min under 550 W. Al these results would lay a founda-tion for exploring a new method for the extraction of polysaccharide from Dendrobi-um huoshanense. |
