Abstract

The headspace solid-phase micro extraction (HS-SPME) procedure coupled with gas chromatography-mass spectrometry (GC-MS) was used to determine profiling volatile components from the roots of Valeriana officinalis and Valeriana edulis ssp. procera. In the two species were identified more than 30 compounds finding terpenoids and aliphatic esters as principal metabolites. The major components in V. officinalis were camphene (31.13%) and bornyl acetate (11.15%), whereas isobutyl isovalerate (46.28%) and methyl isovalerate (13.42%) were the major components in V. edulis ssp. procera.
