SPME-GC-MS分析黄绿蜜环菌子实体挥发性成分

Analysis of Volatile Constituents from the Sporocarp of Armillaria luteo-virens by SPME-GC-MS

利用顶空固相微萃取-气相色谱-质谱联用技术(SPME-GC-MS)研究黄绿蜜环菌子实体的挥发性成分,探讨了不同纤维头取样、不同温度、不同吸附时间等条件对分析检测结果的影响。结果表明,80℃条件下吸附35 min,二乙烯苯/碳分子筛/聚二甲基硅氧烷(DVB/CAR/PDMS)纤维头能够有效地吸附黄绿蜜环菌子实体的挥发性成分;其主要挥发性成分为3,7-二甲基癸烷(13.89%)、姜烯(9.10%)、2,3-二甲基十二烷(8.76%)、佛手柑油烯(4.62%)、十八烷(3.65%)、2-壬酮(3.41%)、2,3,5,8-四甲基癸烷(2.89%)、姜黄烯(2.83%)、6-辛烯-2-酮(2.80%)以及β-红没药烯(2.42%)等。

The volatile constituents from the sporocarp of Armillaria luteo-virens（Alb.et Schwein.：Fr.）Sace.were obtained by solid phase micro-extraction-gas chromatography spectrometry-mass spectrometry（SPME-GC-MS）.The effects of sampling by different fiber hair,temperature and time of adsorption on detecting results were also discussed.The results showed that volatile constituents from the sporocarp could be effectively extracted by the fiber hair of DVB/CAR/PDMS at 80 ℃ for 35 minutes.These volatile compounds mainly included 3,7-dimethyldecane（13.89 %）,zingiberene（9.10 %）,2,3-dimethyldodecane（8.76 %）,α-bergamotene（4.62 %）,octadecane（3.65 %）,2-nonanone（3.41 %）,2,3,5,8-tetramethyldecane（2.89 %）,α-curcumene（2.83 %）,6-octen-2-one（2.80 %） and β-bisabolene（2.42 %）.
