GC-MS分析同时蒸馏-萃取(SDE)黑胡椒挥发性成分

GC/MS determination of volatile compounds in black pepper by simultaneous distillation-extraction

采用同时蒸馏-萃取(SDE)黑胡椒挥发性成分,用色谱/质谱法分析鉴定,并用总离子流色谱峰的峰面积进行归一法定量分析其成分。根据总离子图,分析鉴定出3-蒈稀(27.2%),反式-石竹烯(22.08%),柠檬烯(19.34%),β-蒎烯(9.16%),α-蒎烯(5.15%),l-水芹烯(3.86%),可巴烯(2.32%),δ-檀香烯(2.19%),m-伞花烯(1.88%),β-香叶烯(1.6%)等30种化合物。

The volatile compounds of black pepper were analyzed by GC-MS（gas chromatography-mass spectrometry） analyses.Simultaneous distillation and extraction（SDE） with dichloromethane were used for extraction of black pepper.According to analysis,the aromatic extract obtained by SDE was representative of black pepper odour.The chemical constituent were separated and identified as 3-Carene（27.02%）,trans-caryophyllene（22.08%）,Limonene（19.34%）,beta-pinen（9.16%）,alpha.-Pinene（5.15%）,L-phellandrene（3.86%）,Copaene（2.32%）,delta-elemene（2.19%）,M-cymene（1.88%）,beta-myrcene（1.6%） and so on.A total of 30 compounds were identified.
