Veronica austriaca L. ssp. jacquinii (Baumg.) Eb. Fisch. - GC-MS Peaks of Volatile Compounds

Genus Veronica L. is divided into 13 subgenuses according to morphological traits and it belongs to the Plantaginaceae family. There are 40 species of Veronica in Croatia. They are cosmopolitan and ecologically diverse species spread on a variety of habitats from aquatic, marshy and forest to rock, rock cracks, fields and ruderal habitats. The investigated Veronica jacquinii belongs to Southeast- European- Mediterranean hemicryptophytes. Plant material was collected from Ličko polje (Croatia) and was air dried and water distilled. Composition of volatile compounds was analyzed by GC and GC/MS (Adams, 2007) using VF-5ms capillary column. The peaks appeared from 30 – 59 minutes. Thirteen compounds were determined representing 89% of the total oil. Composition of this essential oil is characterized by a high concentration of hydrocarbon derivatives: hexadecanoic acid (63.5%), followed by octadecanoic acetate (8.9%), oleic acid (6.2%) and heptatriacotanol (3.5%). In our previous research in the oil of V. spicata one of the most abundant hydrocarbon compound was heptacosane (Dunkić et al., 2015). According to a literature review GC-MS studies have been performed only on Veronica thymoides subsp. pseudocinerea and the most abundant constituent was hexatriacontene (21%) (Ertas et al., 2015). The present study gives additional knowledge about volatile compounds of the genus Veronica.
