Usporedba sastava hlapljivih komponenti vrsta Veronica saturejoides Vis. ssp. saturejoides i Veronica austriaca L. ssp. jacquinii (Baumg.) Eb. Fisch

Veronica saturejoides Vis. ssp. saturejoides and Veronica austriaca L. ssp. jacquinii (Baumg.) Eb. Fisch belong to a group of Central European hemicryptophytes of genre Veronica. Using a light microscopy of leaves non glandular trichomes are noticed and glandular trichomes which create secondary metabolites. GC/MS and GC/FID analysis of isolated essential oil of species Veronica saturejoides Vis. ssp. saturejoides are performed. Ten chemical components were identified, most of which are hexahydrofarnesil acetone (65.9%), (E)-methyl isoeugenol (7.9%) and tetracosane (6.3%). The results of the analysis were compared with the literature data of GC / MS and GC / FID analysis of isolated essential oil of Veronica austriaca L. ssp. jacquinii (Baumg.) Eb. Fisch. Out of a total of thirteen chemical components, hexadecanoic acid (63.5%), octadecanol acetate (8.9%), oleic acid (6.2%) and 1-heptatriacotanol (3.5%) are the most common.
