Sažetak
Phytochemicals play critical roles in diverse physiological and pathological processes by participating in biological reactions that are necessary for proper biological functions and plant environment interactions. Therefore, phytochemicals diversity of early vascular or so called "living fossils" are crucial in order to understand metabolic processes which regulate plant adaptations. The main goal of our study was assessment of metabolic diversity in whisk fern Psilotum nudum (L.) P. Beauv as representative of early vascular plants. Extracts from various Psilotum nudum (L.) P. Beauv tissues and organs were subjected to untargeted metabolomic analyses by High Performance Liquid Chromatography – Quadrupole Time of Flight Mass Spectrometry which results in hundreds of diverse metabolites. Predominant metabolites, biflavonoid amentoflavone and signature phenolic glycoside psilotin in areal plant parts od P. nudum were in addition subject for Matrix-Assisted Laser Desorption/I onization Mass Spectrometry Imaging. Our results provide valuable data about ferns phytochemicals and are discussed in the context of the known phytochemicals of extant seedless vascular plants in order to gain a better understanding of the processes that underpin plant evolution in general.
