초록
This research investigated extraction and antioxidant activity of polysaccharides produced from liquid culture of Pleurotus sajor-caju PSC-14. When the ratio of water to sample was increased from 10:1 to 40:1 (mL/g), the polysaccharides extraction yields were increased from 47.2 to 100%. On the other hand, when the ratio increased from 50:1 to 60:1, the yields of polysaccharides extraction were decreased from 80.2% to 62.3%. Extraction yields of polysaccharides were increased with extraction temperature. Especially, when the extraction temperature was increased from 40 to 80 oC, extraction yields of polysaccharides were increased from 41.2 % to 82.6%. On the other hand, at the extraction temperature of 100 oC, there was a little decrease in polysaccharides yield. Maximum extraction yield of polysaccharides was obtained at the extraction temperature of 90 oC. To investigate effect of polysaccharides concentration on antioxidant activity, DPPH scavenging activities were measured. When the polysaccharides concentration was 15.0 mg/mL, the maximum DPPH radical scavenging activity was obtained, 69.25%.
