满山香精油和金橘精油的成分分析及其抗氧化性能研究
Applied Chemical Industry(2020)
Abstract
采用气相色谱-质谱联用法(GC-MS)对满山香和金橘精油的化学成分进行分析,并采用DPPH自由基(DP-PH·)清除法、ABTS自由基阳离子(ABTS+·)清除法对精油及其主要单体的抗氧化性能进行了研究.结果表明,满山香精油鉴定出49个组分的化学成分,占总含量的70.86%,其主要成分为葎草烯(11.71%)和石竹烯(9.22%);金橘精油经鉴定出28种组分,占总含量的96.31%,其主要成分为柠檬烯(70.15%).满山香精油和金橘精油对DPPH·和ABTS+·具有清除活性,其中满山香精油清除DPPH·和ABTS+·的IC50值分别为12.75 mg/mL和1.30 mg/mL;金橘精油清除DPPH·和ABTS+·自由基的IC50值分别为22.34 mg/mL和3.33 mg/mL.
