Abstract: The volatile components in the Fengyoujing were concentrated by head space solid-phase 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 sweet-scented compounds.
