Analysis of the Volatile and Enantiomeric Compounds Emitted by L. Flowers Using HS-SPME-GC.

The volatile components emitted by fresh aromatic flowers of L., harvested in southern Ecuador during three different months were determined to evaluate the fluctuation of secondary metabolites. The volatile compounds were analyzed using headspace solid-phase microextraction (HS-SPME) followed by gas chromatography coupled to mass spectrometry (GC-MS) and a flame ionization detector (GC-FID) using two types of columns: a non-polar (DB-5ms) and polar column (HP-INNOWax).
