【中文摘要】 The Box-Behnken design was used to determine the optimal time,temperature and solvent∶solid ratio for extracting intracellular polysaccharide from G.frondosa mycelium produced under submerged culture conditions.Application of response surface methodology predicted a maximum polysaccharide extraction yield of 7.28% using an extraction time of 2.24 h,an extraction temperature of 92.53 ℃,and a water∶mycelium ratio of 35.76∶1.Under these conditions,the actual yield was 7.15%.Both low(200 mg/kg/d)and...更多 high(500 mg/kg/d)doses of G.frondosa polysaccharide,and positive controls administered 20 mg/kg/d cyclophosphamide,significantly inhibited the growth of S180 tumors with inhibition values of 61.5%,44.42% and 73.8%,respectively compared with negative controls administered physiological saline.  還原
