Analysis of volatile components from <i>Melipona beecheii</i> geopropolis from Southeast Mexico by headspace solid-phase microextraction

<div><p>A head space solid-phase microextraction method combined with gas chromatography–mass spectrometry was developed and optimised to extract and analyse volatile compounds of <i>Melipona beecheii</i> geopropolis. Seventy-three constituents were identified using this technique in the sample of geopropolis collected. The main compounds detected include β-fenchene (14.53–15.45%), styrene (8.72–9.98%), benzaldehyde (7.44–7.82%) and the most relevant volatile components presents at high level in the geopropolis were terpenoids (58.17%).</p></div
