Sažetak
European speedwell is a widespread and well known species among the population. It is commonly known to be edible in the period before flowering. Therefore, the aim of this study was to compare the composition of free volatile compounds extracted in the lipophilic part and in the aqueous part (hydrosol) of the aerial parts of Veronica beccabunga L. (Plantaginaceae). This comparison is important for the selection of the extract for further biological studies. Two extraction methods were used: the classical one (hydrodistillation, HD) and a new technique (microwave-assisted water extraction, MAE). Gas chromatography-mass spectrometry was used to identify the volatile compounds in two phases of the two extractions, i.e., in four samples. The main components in the hydrosol HD sample are: piperitone (28.15%), benzene-acetaldehyde (13.23%) and trans-p-mentha- 1(7), 8-dien-2-ol (10.3%), while in the MAE hydrosol sample piperitone is the main compound with 79.86%. The oxygenated diterpene phytol (27.31%) and the two hydrocarbons, hexacosane (16.21%) and heptacosane (14.89%), are the predominant compounds in the lipophilic HD extract. Piperitone (29.28%) and phytol (34.54%) are the predominant compounds in the lipophilic MAE extract. Comparing these two extraction methods, the method MAE is more environmentally friendly due to the working conditions. From the obtained results, it is clear that hydrosols should not be classified as extraction waste, as they are a valuable source of bioactive compounds. Due to the richness of volatiles, Veronica beccabunga is important for further research. Considering the wide distribution of this plant, the material is easy accessible for research and application.
