摘　　要：采用水蒸气蒸馏法提取南天竹花挥发油,利用气相色谱-质谱联用技术分析挥发油化学成分;以ABTS自由基清除作用、金属离子螯合作用为指标评价20%挥发油的体外抗氧化活性。从南天竹花挥发油中共鉴定出60种化合物,占挥发油总量的76.98%,主要成分为棕榈酸、棕榈醛、十八烷醛、3,7-二甲基-1,5,7-辛三烯-3-醇、1-十六烯等;挥发油对ABTS自由基和金属离子具有较好地清除作用和螯合作用,且样品量与活性呈量效关系。The volatile oil from the flowers of N. domestica was extracted by water-steam distillation and analyzed by GC-MS. The an-tioxidant activity in vitro of 20%volatile oil was evaluated by scavenging capacity against ABTS·and metal chelating ability. Sixty compounds,which occupied 76. 98%of total constituents,were identified from the volatile oil. The major constituents were palmitic acid,hexadecanal,octadecanal,3,7-dimethyl-1,5,7-octatriene-3-ol,1-hexadecene. The volatile oil exhibited significant scavenging capacity against ABTS·and metal chelating ability in a concentration-dependent fashion.
