摘　　要：利用树舌深层发酵法制备富锗胞内多糖,并测定其体外抗氧化活性。结果表明:氧化锗在250μg/mL质量浓度时,对胞内多糖产量及有机锗的含量有显著提高,同时富锗胞内多糖对超氧自由基(O.-2)、羟基自由基(.OH)、DPPH.及亚硝酸盐有较好的清除作用,且还原能力较强。Germanium-rich intracellular polysaccharides（GIPS）were prepared via at-depth fermentation of Ganoderm applanatum,and the antioxidative activity of GIPS in vitro was evaluated.Results showed that 250 μg/mL of germanium dioxide in the culture promoted the content of intracellular polysaccharide,organic germanium.At the same time GIPS had strong scavenging effective to super-oxide anion radical,DPPH.,nitrite and hydroxyl radical,and the function of anti-oxidative became stronger,and had strong reducing ability.
