Con.1 was the constituent of high molecular weight and the other three were all of low molecular weight. Micro_Kjeldahl analysis showed that Con.1 contained 3.95% of nitrogen and neither did the other three parts. The antisenile effects of the four parts of ABPS were studied with Drosophila melanogaster. Results showed that Con.1 has no antisenile effect and all the others could significantly increase the average body weight by 3.85%-5.47% and significantly prolonged the average lifespan by 2.61%- 3.16% of D. melanogaster at the concentration of 2 or 5 mg/g (ABPS/medium).展开更多
研究了中药黄芪对灵芝发酵生产灵芝多糖的影响,确定了黄芪添加的可行性及最适添加量,并对发酵产生的粗多糖进行分析,通过 Sephadex G 75 凝胶对粗多糖进行初步分离和研究.结果表明:黄芪有利于灵芝在发酵中多糖的产生,其多糖的组分发生变...研究了中药黄芪对灵芝发酵生产灵芝多糖的影响,确定了黄芪添加的可行性及最适添加量,并对发酵产生的粗多糖进行分析,通过 Sephadex G 75 凝胶对粗多糖进行初步分离和研究.结果表明:黄芪有利于灵芝在发酵中多糖的产生,其多糖的组分发生变化,有可能产生新的物质.展开更多
