Our project collaborators Dario Kremer and Marija Nazlić presented a research within the project on the IUBMB–FEBS–PABMB Congress. Congress was held in Lisbon, July 09 – 14, 2022. They presented their research with a poster presentation entitled „ Green extracting as a contribution to sustainability: the case of Veronica officinalis L. “. To gain insight into the differences between hydrodistillation (HD) and microwave extraction (ME), FVCs (free volatile compound) extracted from the aerial parts of Veronica officinalis L. were investigated. It is precisely because of the phytochemical constituents of the studied species, that V. officinalis L. is used in the traditional medicine. HD and ME extracts consist of an oil part and the water part (hydrosols). In this research FVCs of both parts were analyzed by gas chromatography combined with mass spectrometry.
