ABSTRACT: The study of the volatile
components of the leaves, stems and flowers of Vernonanthura patens is discussed. A micro solid-phase extraction at
constant temperature with a dimethylsiloxane fiber of 100 μm was performed. The compounds extracted were analyzed by gas chromatography
coupled to mass spectrometry (GC-MS). 7 monoterpenes structures were assigned to
leaves, and three to stems, these compounds were not detected in the flowers with
the configuration of the system used. 17 sesquiterpenes were identified in the leaves;
6 in stems and 2 in flowers, finding coincidence in some of them. The major components
were α-humulene in leaves, bergamotene in stems and caryophyllene
in flowers.
