Veronica cymbalaria Bodard – When the GC-MS Peaks of Volatile Compounds Appear

Genus Veronica L. belongs to the Plantaginaceae family, and according to morphological traits, it is divided into 13 subgenuses. In Croatia, plant species of genus Veronica are spread on a variety of habitats from aquatic, marshy, forest, carbonate, mountain pastures and mountain limestone caves to rock and rock cracks, fields and ruderal habitats. The investigated species Veronica cymbalaria belongs to South-European-Mediterranean terophytes. Plant material was collected from Split (Croatia), in the spring (April) 2015. Water distilled essential oils from aerial parts of investigation plant have been analyzed by GC and GC/MS (Adamas, 2007) using VF-5ms capillary column and the first peaks appear after 30 minutes. The total yield of oil was 0.1%, based on dry weight of samples. Ten compounds were determined representing 89.5% of the total oil. Composition of this essential oil is characterized by a high concentration of phytol (59.7%), several different hydrocarbons (in total 14.1%) and caryophylene oxide (5.1%). In our previous research phytol was also identified in the oil of V. spicata (Dunkić et al., 2015). In our review, we found one more species, Veronica thymoides subsp. pseudocinerea, that was investigated with the same methodology. Compound peaks for V.thymoides also appeared after 30 minutes of the GC-MS analysis and the most abundant constituent was hexatriacontene (21%) (Ersat et al., 2015). The present study gives additional knowledge about chemosystematic profile of the genus Veronica.
