摘 要:采用固相微萃取技术(SPME)吸附香樟木质部挥发性成分,结合气相色谱-质谱(GC/MS)进行化学成分的分离和鉴定,同时比较不同色谱柱对分离效果的影响。结果表明:采用弱极性DB-5MS色谱柱共分离出51个组分,解析出43种挥发性成分,占总峰面积的97.04%,分离效果和所得的峰形较好于DB-WAXetr色谱柱。鉴定出含量较高的成分有:左旋-α-蒎烯(4.57%)、莰烯(2.14%),双环[3.1.0]-4-甲基-1-异丙基-2-己烯(4.16%)、β-蒎烯(2.3%)、邻异丙基甲苯(2.15%)、D-柠檬烯(7.49%)、桉叶油醇(13.85%)、樟脑(38.71%)、(R)-4-萜品醇(1.74%)、α-松油醇(2.40%)、黄樟素(2.96%)、α-荜澄茄油烯(4.36%)、1-石竹烯(1.92%)等。该方法可为香樟材在医药、食品和化学工业等方面的进一步开发和利用提供参考。The volatile components of Cinnamomum camphora xylem were extracted by solid phase microextraction(SPME) and were identified by gas chromatography-mass spectrometry (GC/MS).The separation efficiency of different chromatographic column was compared as well.The results show that GC/MS spectrometric analysis with DB-5MS isolates 51 components,which contains 43 kinds of volatile content,and the proportion of the peak area of volatile components is 97.09 %.The separation efficiency and the peak shape of GC/MS spectrometric analysis with DB-5MS are superior to that with DB-WAXetr.Based on the identification of the volatile components,(1S)-α-pinene(4.57%),camphene(2.14%),bicyclo[3.1.0]-4-methyl-l-(1-methylethyl)-hex-2-ene(4.16%),β-pinene(2.3%),1-methyl-2-(1-methylethyl)-benzene(2.15 %),D-limonene (7.49 %),eucalyptol (13.85 %),camphor(38.71%),(R)-4-terpineol(1.74%),α-terpineol(2.40%),safrole(2.96%),α-cubebene (4.36%) and caryophyllene(1.92%) account for most of them.The method can provide a reference for the further development and utilization of Cinnamomum camphora in medicine,food and chemical industry,etc.
