摘　　要：选用燕麦、大豆、玉米、麸皮、大米、荞麦6种培养基质,对猴头菌进行固体发酵及抗氧化活性研究。结果表明:猴头菌最佳抗氧化发酵基质为荞麦大豆培养基(荞麦79.13%,大豆20.87%),最佳发酵条件为温度30℃,培养料粒度40目,培养基含水量70%,初始pH值4,接种量4.5%,发酵时间12d。猴头菌荞麦发酵基质抗氧化活性成分种类丰富,含量高,其中总黄酮物质87.13μg/g,总三萜2.58mg/g,多酚4.51mg/g,还原糖21.53mg/g,花色苷68.96μg/g,VC14.07mg/g,VE205.85μg/g,GSH 853.65mg/g,SOD酶活性293.57U/g。Hericium erinaceum was cultured on the medium including oat, wheat bran, soybeans, corn, rice and buckwheat with solid-state fermentation, and then was determined the best fermentation time and was analyzed antioxidant components of substrate. The results show that the best antioxidant fermentation substrate of I-Iericium erinaceum was buckwheat and soybeans complex medium （79. 13% buckwheat and 20. 87%, soy beans）, the optimum fermentation temperature for 30 ℃, material grain size for 40 mesh, medium moisture for 70%, initial pH for 4, inoculation for 4. 5%, and the best fermentation time was 12 d. The antioxidant components of Hericium erinaceum substrate with buckwheat were rich in varieties and high in contents, such as flavonoids 87. 13 μg/g, total triterpenoid 2. 58 mg/g, total polyphenols 4.51 mg/g, reducing sugar 21.53 mg/g, anthocyanins 68.96μg/g, Vc 14.07 mg/g, VE205. 85 μg/g, GSH 853.65mg/g,SOD activity 293.57 U/g.
