essential oil of O. fragrans has demonstrated that its composition
is very different at different stages of Osmanthus flower development
(Yang & Zhu, 2000).
Until now, few studies have reported the analysis of the essential
oil at different stages of Osmanthus flowering. In this work, we
propose a method for the rapid analysis of volatile compounds released
at four different stages from living Osmanthus flowers, using
headspace solid-phase microextraction (HS-SPME) and gas chromatography–
mass spectrometry (GC–MS). In this study, we report
the variation of chemical composition of different flowering stages,
in order to determine the optimal harvest time for O. fragrans
