摘要:

采用水蒸气蒸馏法从广藿香中提取挥发性成分的油相成分,用乙醚作为溶剂从蒸馏废液中萃取挥发性成分的水溶性成分,利用气相色谱-质谱联用(GC-MS)分析二者的化学组成。油相成分的主要成分为广藿香醇(34.72%)、广藿香酮(12.02%)、δ-愈创木烯(7.53%)、西车烯(6.69%)。水溶性挥发成分中不含萜烯类化合物,广藿香酮(21.89%)在水溶性成分中含量最高。采用DPPH自由基(DPPH·)清除法和ABTS阳离子自由基(ABTS+·)清除法对广藿香挥发性成分的抗氧化性能进行了研究。结果表明广藿香挥发性成分的水溶性成分对DPPH·和ABTS自由基的清除能力远远强于油相成分,广藿香水溶性挥发性成分和油相成分清除DPPH·的IC50值分别为0.187 0和6.489 9 mg/mL,清除ABTS+·IC50值分别为4.662×10-2 和0.998 5 mg/mL。

Abstract:

The oil fraction of the volatile components from Pogostemon cablin (Blanco) Benth was obtained through hydrodistillation,and ether was used as solvent to extract the water-soluble fraction of the volatile components from the distilled waste liquid.The volatile components from P.cablin were analyzed by gas chromatography-mass spectrometry (GC-MS).The major constituents in the oil fraction were patchouli alcohol (34.72%),pogostone (12.02%),δ-guaiene (7.53%),and seychellene (6.69%).There were no terpenes in the water-soluble fraction in which pogostone (21.89%) was the principal constituents with the highest content.The antioxidant activity of the volatile components was tested by DPPH· scavenging method and ABTS+· scavenging method.The results showed that the water-soluble fraction of the volatile components from P. cablin possessed higher scavenging activities on DPPH· and ABTS free radicals than the oil fraction.The IC50 values scavenging on DPPH· of water-soluble fraction and oil fraction were 0.187 0 and 6.489 9 mg/mL,the IC50 scavenging on ABTS+· were 4.662×10-2 and 0.998 5 mg/mL,respectively.
