HS-SPME-GC/MS法分析风油精中挥发性成分

摘要

The volatile components in the Fengyoujing were concentrated by head space solidphase micro-extraction(HS-SPME), and analyzed by gas chromatography-mass spectrometry (GC/MS). 27 components are identified. The principal components are methyl salicylate (25. 19％), menthol (23. 25％), eugenol (7. 86％), eucalyptol (7. 28％), camphor (6.62％), phenethyl alcohol (6.35％) and benzyl acetate (5.73％). Some components have the action of sterilization, diminishing inflammation, stanching itch and demulcent, such as methyl salicylate, menthol, eugenol and camphor. Many volatile components are sweetscented compounds.%采用固相微萃取-气相色谱-质谱法分析风油精中的挥发性成分.共检测出27种化合物,含量较高的有水杨酸甲酯(25.19%)、薄荷脑(23.25%)、丁香酚(7.86%)、桉树脑(7.28%)、樟脑(6.62%)、苯乙醇(6.35%)和乙酸苯甲酯(5.73%)等.水杨酸甲酯、薄荷脑、丁香酚和樟脑等均具有杀菌消炎和止痒镇痛的作用,并且多种成分具有特殊的香气.
