摘要
对固相微萃取(solid phase micro-extraction,SPME)技术萃取香草兰中挥发性成分的萃取条件进行优化,并采用SPME和同时蒸馏萃取(simultaneous distillation extraction,SDE)两种方法对海南地区香草兰豆荚中挥发性成分进行检测分析。结果表明:SPME最优萃取条件为萃取头75μm CAR/PDMS、萃取温度80℃以及萃取时间20 min。2种萃取方法共检测出105种挥发性成分,其中利用SPME技术检测出挥发性成分73种,SDE检测出78种。结果表明:将SPME和SDE两种方法联合使用可以更加全面地检测出香草兰中的挥发性成分。
The conditions of solid phase micro-extraction （SPME） for extraction of volatile components in vanilla grown in Hainan were optimized and its effectiveness was compared with that of simultaneous distillation extraction （SDE） for the analysis of volatile components in vanilla by gas chromatography coupled with mass spectrometry （GC-MS）. The results showed the optimal SPME conditions were established using a 75 μm carboxen /polydimethylsiloxane （CAR/PDMS） fiber at 80 ℃ for 20 min. A total of 105 volatile components were identified, among which, 73 volatile compounds were extracted by SDE and 78 by SPME. This study has shown that more volatile components can be extracted and identified with a combination of SPME and SDE.
