摘要: 筛选了浓香乳菇液体深层发酵培养基,研究了浓香乳菇菌丝体对脂类过氧化物的抗氧化活性。结果表明,低温烘干对抗氧化活性组分提取影响不大,粉碎过筛起着较好的抽提效果,但高温烘干应慎重;索氏提取对抗氧化组分活性有较大的影响,不宜作为提取方法应用;以硫氰酸铁法快速检测 500nm吸光度值,选定 80%乙醇为最佳提取试剂。用 Na2S2O3- I2滴定法测了对猪油的抗氧化作用,发现浓香乳香菇菌丝体提取物的抗氧化效果显著, VE、 VC有一定的增效协同作用。

Abstract:  The resistance to lipid peroxidation of the sfudy on Resistance fo Lipid peroxidation of Lacfarius camphoratus mycelium myceliam hyphostroma of Lactarius camphoratus was studied.The extracting effects by different methods and different pretreatment of the samples were compared by the thiocyanate method.The concentration of extract regent was ascertainted.The antioxidative activities of 80% ethanolic extracts were evaluated in lard by Na2S2O3- I2.The result showed that the citric acid、 tartaric acid、 VC、 VE demonstrated better synergistic effect.

Key words: Lactarius camphoratus Hyphostroma Flavone Antioxidant activity
