The objective of the work reported in this paper was to evaluated effects of temperatures extraction on in vitro antioxidant activities of polysaccharides from the Ophiocordyceps sobolifera. The antioxidant capacity of Ophiocordyceps sobolifera polysaccharide was evaluated to use 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and total antioxidant activity methods. From this study, it could be concluded that the highest antioxidant activity of the polysaccharides could be obtained from extraction temperature 80 o C. Total antioxidant capacity of polysaccharides from Ophiocordyceps sobolifera contained from 0.1183 ± 0.0011 to 0.1454 ± 0.0021 mg GA/g or from 0.1105 ± 0.0004 to 0.1215 ± 0.0006 μmol AS/g. Polysaccharides has the most potential antioxidant activity with the lowest half maximal inhibitory concentration (IC 50 ) value range 0.97 mg/mL to 1.06 mg/mL.
