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
