Abstract:
Headspace solid-phase microextraction coupled to gas chromatography and mass
spectrometry (HS-SPME-GC/MS) has been optimised for the analysis of volatile
compounds in six samples of rose petals (Rosa Mariyo, Rose Tara, Rosa Rhodos,
Rosa Sudoku, Rosa Deep Purple, Rosa Tacazzi). Volatiles from roses were
extracted using a SPME fibre by carrying out the subsequent separation and
identification by comparison of their mass spectra with mass spectra libraries and
retention indexes. Several factors influencing the SPME were taken into account;
namely, extraction time, extraction temperature and the sample weight. The
optimal parameters of the extraction of volatile compounds were obtained based
on statistical evaluation; the most suitable conditions being the extraction time of
60 min., the extraction temperature of 90 °C and the sample weight of 0.7 g.
