采用顶空固相微萃取-气相色谱-质谱联用技术检测分析了柚木光辐射前后的挥发性成分,研究结果表明:从光辐射前后的柚木中共鉴定出80种挥发性成分,辐射前(原柚木)鉴定出57种挥发性成分,辐射60 h后的柚木中鉴定出53种挥发性成分,包括烃类、醇类、酚类、酯类、醛类、酮类、蒽醌类和胺类。光辐射后柚木未能检测到酮类,且醇类从12. 586%减少到7. 498%,醇类化合物由6种减少至3种,醛类从0. 404%增加到3. 653%,醛类化合物由3种增至5种。柚木光辐射前挥发性成分主要是2-甲基蒽醌(18. 443%) 、2-N-甲基-萘胺(14. 781%) 、邻苯二甲酸异丁基辛基酯(9. 567%) 、1,2,3-三甲基-4-丙烯基-(E)-萘(7. 513%) 、τ-杜...

Headspace solid-phase micro-extraction (HS-SPME) combined with gas chromatography-mass spectrometry (GC-MS) technology was used to analyze the volatile constituents in original and irradiated Tectona grandis L.F.. The results showed that 80 kinds of volatile constituents were identified. There were 57 volatile constituents in T. grandis without irradiation and 53 volatile constituents in T. grandis after irradiation. They included hydrocarbons, alcohols, phenols, esters, aldehydes, ketone, anthraquinone and amine. After irradiation, the ketone ...
