Studies of the Volatile Compounds Present in Leaves, Stems and Flowers of Vernonanthura patens (Kunth) H. Rob.

Description: 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 ?m 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 ?-humulene in leaves, bergamotene in stems and caryophyllene in flowers.
