| 摘 要： | 采用GC-MS测定了海南文昌小叶杜拉种(E.guineensis-S.L.Dura)油棕果中棕榈油(PO)和棕榈仁油(PKO)的脂肪酸组成,并对二者的体外抗氧化活性进行评价。结果表明,PO中总酚含量为(0.014±0.000 2)mg/g,而PKO中未测出多酚;PO及PKO的硫代巴比妥酸值(TBARS)显著低于空白样品;75%PO对DPPH.的清除能力显著高于Vc、苹果酸和儿茶酸,达98.86%,而PKO对DPPH.的清除能力低于对照;PO中多酚提取物(PO-PF)及75%PKO对Fe2+的络合能力显著高于Vc、苹果酸和儿茶酸;PO-PF和75%PO对Fe3+的还原能力显著高于Vc及苹果酸,75%PKO对Fe3+的还原能力与Vc相当。PO-PF及25%～75%PKO对ABTS+.的清除能力优于Vc和苹果酸。
