Abstract: 以白色甜味,红色甜味和红色酸味3种石榴栽培品种(分别为临潼‘三白甜’(SBT)、‘净皮甜’(JPT)和‘酸石榴’(SSL))的果实为原料,通过石油醚超声波辅助提取法获得籽油样品,采用气相色谱-质谱法(GC-MS)分析其脂肪酸组成的差异性,并研究这些籽油的自由基清除能力及其皂化产物的抗氧化性.结果表明:3种石榴籽油(PSO)的主要组分的含量差异较大,含量最高的脂肪酸均为石榴酸,其含量大小顺序为‘三白甜’籽油>‘净皮甜’籽油>‘酸石榴’籽油.3种石榴籽油对DPPH·和ABTS+·均有较强的清除作用,且呈量效关系,其皂化产物(脂肪酸盐)则具有良好清除·OH和抑制β-胡萝卜素/亚油酸体系漂白的作用,而且3种油及其皂化产物的抗氧化性强弱排序相同,均为SBT> JPT> SSL,这提示石榴籽油中的石榴酸最可能是其关键的抗氧化成分.这些发现可为石榴籽油的进一步研发提供依据.
