摘要:

为明晰采收后向日葵盘精油的成分及其体外抗氧化活性,应用水蒸气蒸馏法提取采收后向日葵盘精油,利用气相色谱-质谱联用法(GC-MS)分析其化学成分,通过DPPH自由基和ABTS自由基清除法对精油的体外抗氧化活性进行测定。结果显示:从向日葵盘精油中共鉴定出49种化学成分(占精油总量91.16%),其中α-蒎烯(28.22%)、柠檬烯(6.55%)、α-蛇麻烯(4.99%)、反式-β-金合欢烯(3.58%)和莰烯(3.39%)为其主要成分。向日葵盘精油具有一定的体外抗氧化活性,其清除DPPH自由基、ABTS自由基的半数有效浓度(EC50)值分别为0.47、0.30 g/L,明显高于阳性对照BHT的EC50值(分别为8.21和6.16 mg/L)。

Abstract:

The essential oil of Helianthus annuus head which harvested in autumn was extracted by water-steam distillation, and it's components was characterized by gas chromatography-mass spectrometry(GC-MS). The in vitro antioxidant activities of essential oil were studied by 2, 2-di(4-tert-octylphenyl)-1-picrylhydrazyl(DPPH) and 2, 2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) radical scavenging assay. The GC-MS analysis showed 49 kinds of chemical components(comprising 91.16% of the essential oil) were identified from the essential oil of H. annuus head, and α-pinene(28.22%), limonene(6.55%), α-humulene(4.99%), trans-β-farnesene (3.58%) and camphene (3.39%) were the main ingredients. The essential oil had some in vitro antioxidant activity, and the half effective concentration(EC50) of the essential oil against DPPH and ABTS radical were 0.47 and 0.30 g/L, respectively, which significantly higher than that of BHT(8.21 and 6.16 mg/L).
