Effect of extraction temperatures on in vitro antioxidant activities of polysaccharides from Ophiocordyceps sobolifera
The objective of this paper is to evaluate the effects of extraction temperatures on in vitro antioxidant potential of polysaccharides from the Ophiocordyceps sobolifera. The antioxidant capacity of Ophiocordyceps sobolifera polysaccharides was evaluated using 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) as...
