摘要: 采用超临界CO2萃取珊瑚姜得到珊瑚姜油,添加到在烘箱强化保存条件下(60~65℃)的浓缩鱼油中,测定鱼油的过氧化值(POV),考察珊瑚姜油对浓缩鱼油的抗氧化能力;并用气相色谱-质谱联用仪(GC-MS)对珊瑚姜油进行分析,从化学组成探讨珊瑚姜油与BHT和VE对鱼油的抗氧化机理差异。结果表明:珊瑚姜油抗氧化效果优于BHT及VE,是一种良好的天然抗氧化剂,珊瑚姜油添加量为0.03%时对鱼油很好的保护作用;GC-MS方法鉴定出珊瑚姜油有44种成分:单萜类化合物13种,占25.12%;含氧单萜类化合物16种,占26.43%;倍半萜类化合物9种,占8.82%;含氧倍半萜、苯系衍生物及其他6种,占39.63%。

Abstract: A natural plant essential oil was extracted from Zingiber corallinum Hance as a common herb for Miao ethnic minority in Guizhou by supercritical carbon dioxide extraction. The antioxidant activity of the essential oil was evaluated by comparing changes in the peroxide value (POV) of concentrated fish oil during storage at 60-65 ℃ in the respective presence of the essential oil, vitamin E (VE) and butylated hydroxytoluene (BHT). Forty-four compounds were identified in the essential oil by GC-MS, including 13 monoterpenoids (25.12%), 16 oxygen-containing monoterpenoids (26.43%), 9 sesquiterpenes (8.82%) and 6 oxygen-containing sesquiterpenes, benzene derivatives or others (39.63%). The essential oil as a natural antioxidant was superior to VE and BHT. The fish oil can be protected effectively by adding 0.3% essential oil.

Key words: essential oil from Zingiber corallinum Hance, supercritical carbon dioxide extraction, concentrated fish oil, VE, butylated hydroxytoluene (BHT), antioxidant
