[ Objective ] The aim was to study the effects of polysaccharides of Dendrobium Huoshanense and Dendrobium moniliforme on oxygen free radicals and lipid peroxidation in vitro. [ Method] The scavenging action on .OH of polysaccharides, the inhibition action on O2^- of polysaccharides, MDA production of lipid peroxidation were measured by Fenton reaction, self oxidation system of C6H3( OH)3 and TBA method respectively. [ Result] The half scavenging concentration on ·OH of potysaccharides of Dendrobium Huoshanense and Dendrobium moniliforme was 6.79 and 6.75 mg/ml respectively. As to their half inhibition concentration on O2 , the data was 3, 04 and 3.44 mg/ml respectively. Two kinds of Dendrobium polysaccharides bothhad inhibitory actions on lipid peroxidation of liver homogenate induced by auto-oxidation and inducedoxidation, and they could alleviate oxidation damages of mice liver mitochondria induced by Vc-Fe2+ system. [Conclusion] Two kinds of Dendrobium polysacchaddes both had remarkable anti-oxidation activity in vitro. 展开更多

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. 展开更多
