Extraction, Composition and Comparisons–Free Volatile Compounds from Hydrosols of Nine Veronica Taxa

The extraction of bioactive plant components, which belong to specialized metabolites, is carried out by conventional and novel methods. In this study, a classical (hydrodistillation, HD) technique (microwave-assisted water extraction, MAE) were used isolate free volatile compounds from nine Croatian Veronica taxa (family Plantaginaceae). Each these extracts consists lipophilic phase an aqueous (hydrosol). Gas chromatography-mass spectrometry was identify the in hydrosol studied Veronica. β-ionone benzene acetaldehyde detected all hydrosols studied. Other abundant investigated species are germacrene D, α-muurolol, (E)-β-damascenone, β-ionone. Also, compositions phases (published our previous research) compared. Identification both extract parts important for selecting part further biological research. According distribution PCA analyses comparing two methods, only showed greater difference composition therefore conclusion that most there no significant composition. Microwave better choice with regards more environmentally friendly working conditions. Furthermore, we conclude not waste products, but valuable source great potential applications.
