 +Later on, headspace analysis of hyacinth flowers showed that 2,6-dimethylocta-1,3,5,7-tetraenes and 2,6-dimethylocta-3,5,7-triene-2-ols are associated with charcoal as adsorbing material. It was shown that these compounds are artefacts from ocimene which mainly arise during sampling with charcoal.
