Optimization for the extraction of polysaccharides from Gentiana scabra Bunge and their antioxidant in vitro and anti-tumor activity in vivo 作者:Wang, CY (Wang, Chenyu)[ 1 ] ; Wang, Y (Wang, Yan)[ 2 ] ; Zhang, J (Zhang, Jing)[ 1 ] ; Wang, ZY (Wang, Zhanyong)[ 1 ] JOURNAL OF THE TAIWAN INSTITUTE OF CHEMICAL ENGINEERS 卷: 45 期: 4 页: 1126-1132 DOI: 10.1016/j.jtice.2013.12.004 出版年: JUL 2014 查看期刊信息 摘要 Water-soluble polysaccharides were obtained from Gentiana scabra Bunge. Response surface methodology was used to optimize the extraction conditions, and a central composite design was adopted to determine the optimal processing parameters. The optimum extraction conditions are as follows: extraction temperature, 100 degrees C; ratio of water to raw material, 26.56; extraction time, 3 h; and extraction frequency, 2. Under these conditions, the experimental yield of polysaccharides was 13.0 +/- 0.25%, which was consistent with the predicted yield. In vitro evaluation of the antioxidant activity suggests that the polysaccharides have high scavenging activity to 1,1-dipheny1-2-picrylhydrazyl radicals, relatively lower reducing power and scavenging activity to superoxide anions and hydroxyls. The polysaccharides also show high anti-tumor activity in vivo. (C) 2013 Taiwan Institute of Chemical Engineers. Published by Elsevier B.V.
