Abstract: The ethanol extract conditions propolis by and their antioxidant activities were studied simultaneously. The resultsshowed the best extract conditions was: ethanol concentration 94.51%, extracting temperature 34.44℃, extracting time 33.86hand ratio of propolis to liquid 1:15.91 by orthogonal test according to Responds Surface Methodology. Anti-oxidative effect ofethanol extract of propolis(EEP)on lard was studied.The results showed that EEP could inhibit the reaction of lipid peroxidationof oil significantly. The anti-oxidative effect of EEP on lard was better than VE and tea polyphenols. Propolis was a potentialproducts of natural ,safe and effective antioxidant.

Key words: propolis, ethanol, extract, anti-oxidative effect, responds surface methodology
