摘　　要：植酸水解得到1,2,6-三磷酸肌醇(PP56),PP56与三乙胺反应生成相应的铵盐。以二氯甲烷为溶剂,脂酶Novozyme435催化,该铵盐与乙酸反应生成1,2,6-三磷酸-3,4,5-三乙酸肌醇酯。以过氧化值(POV)为指标研究不同剂量的1,2,6-三磷酸-3,4,5-三乙酸肌醇酯对菜籽油的抗氧化性能,结果表明:1,2,6-三磷酸-3,4,5-三乙酸肌醇酯对菜籽油具有明显的抗氧化作用且存在剂量效应关系,在浓度为0.06%时其抗氧化能力和0.02%BHT相当。1,2,6-triphosphate inositol（PP56） was prepared by hydrolyzing phyUc acid. The ammonium salt of PP56 was produced when it reacted with triethylamine. The 1,2,6-triphosphate -3,4,5-triacetate inositol was synthesized when PP56 reacted with acetic acid catalyzed by iipase Novozyme 435 in dichloromethane. The antioxidative activities were evaluated in rapeseed oil by using peroxide value. It revealed that 1,2,6- triphosphate-3,4,5-triacetate inositol showed obvious antioxidant activities in rapeseed oil and its＇effects were enhanced with increased amount. The antioxidative ability of 0.06% 1,2,6-triphosphate-3,4,5-triacetate inositol was almost equal to that of 0.02% BHT.
