摘　　要：以硫代巴比妥酸法(TBA法)和过氧化值法(POV法)测定了二氢杨梅素(DMY)对猪油和植物油的抗氧化作用。结果表明:随着提取纯度的增加,DMY对油脂的抗氧化性增强。在猪油上,三种纯度的DMY的抗氧化作用均优于同浓度的TBHQ;在植物油上,DMY在前期的抗氧化效果优于TBHQ,后期与TBHQ相近。DMY作为天然抗氧剂可以应用于油脂及高油食品的保藏上。The antioxidation of DMY on lipid peroxidation was studied, the result showed that DMY could inhibit the reaction of lipid peroxidation significantly, and delay the inducement period. The antioxidatory activity of DMY increased with the increment of purity and to lard, The effect of DMY was better than TBHQ at the same concentration .the results in plant oil showed the effect of DMY in former period was better than TBHQ, there was no significant difference in later period.
