Extraction of polysaccharides from Phellinus nigricans mycelia and their antioxidant activities in vitro 作者:Wang, ZY (Wang, Zhanyong)[ 1 ] ; Wang, CY (Wang, Chenyu)[ 1 ] ; Quan, Y (Quan, Yue)[ 1 ] CARBOHYDRATE POLYMERS 卷: 99 页: 110-115 DOI: 10.1016/j.carbpol.2013.08.073 出版年: JAN 2 2014 查看期刊信息 摘要 In this study, response surface methodology was employed to optimize the extraction of polysaccharides from Phellinus nigricans mycelia. A central composite design was adopted to determine optimum parameters (extraction time, extraction temperature, extraction frequency, and ratio of water to raw material) that could yield a maximum polysaccharide. Results revealed the following optimum extraction conditions: extraction time, 2.8 h; ratio of water to raw material, 28; extraction frequency, 5; and extraction temperature, 95 degrees C. Under optimized conditions, the experimental yield of P. nigricans mycelia polysaccharides was 15.33 +/- 0.21%, which is consistent with the predicted yield. The antioxidant activity assay in vitro showed that the polysaccharides exhibited a high scavenging activity against superoxide anion, hydroxyl, and 1,1-diphenyl-2-picrylhydrazyl radicals. These polysaccharides also exhibited a strong reducing power. Thus, these polysaccharides can be used as natural antioxidants in functional foods or medicine. (C) 2013 Elsevier Ltd.
