Natural fragrances from lemon verbena ( Aloysia triphylla ) were studied by headspace solid phase microextraction (HS‐SPME) techniques followed by gas chromatography‐mass spectrometry (GC‐MS), with six different fibre coatings being tested to evaluate the extraction efficiencies of several selected compounds. A total of 14 compounds were identified in the fragrances of lemon verbena. Geranial and neral were detected as major components and α‐pinene, β‐pinene, β‐caryophyllene, and curcumene as minor components. Enantiomeric analysis of chiral compounds from lemon verbena was carried out on a chiral column. α‐Pinene, limonene, and camphor in the fragrances emitted from lemon verbena were found in the (+), (–), and (–) forms, respectively.
