we determined the partition coefficients, PWO, of four series of potent, natural AOs of increasing lipophilicity between vegetable oils (olive, soybean, and corn) and water and, for the sake of comparison, between octanol–water, PWOCT. Results indicate that the contribution of the −CH2 groups to the overall lipophilicity of the AO is the same irrespective of the oil employed. The PWO values were compared
尽管AOs被广泛用于控制脂质的氧化和细胞中的氧化应激,但在食用油和水之间的抗氧化剂(AOs)的分配系数P W O却很少。P W O值对于预测从二元油水系统到活细胞的不同生物组织水平的生物活性物质的效率和分布非常重要。在这里,我们确定分配系数,P w ^ ō,四大系列增加植物油(橄榄油,大豆和玉米)和水之间的亲脂性进行比较的缘故有力的,自然的AO的,辛醇-水之间,P世界华侨城。结果表明,与所用的油无关,-CH 2基团对AO整体亲脂性的贡献是相同的。将P W O值与P W OCT值进行比较,并获得每个AO系列的线性关系。结果表明,通常不能从P W OCT值预测P W O值,因此有必要确定每种油和抗氧化剂的P W O值。
