Abstract

We investigate a correlation between the microelement profile and the essential oil composition of a plant by taking the plants from the Filipendula genus as an example. The following plants from the meadowsweet genus growing in Eurasia are used as study subjects: F. angustiloba Maxim., F. сamtschаtica Maxim., F. denudata Fritsch., F. glaberrima Nakai, F. intermedia Juz., F. palmata Maxim., F. picbaueri Smejkal. F. ulmaria Maxim., and F. vulgaris Moench. Fifty nine microelements are determined by inductively coupled plasma mass spectrometry. The composition of essential oils from these plants is determined by gas chromatography mass spectrometry. It is established that the compositional profile of volatile components of their essential oils consists of 19 phenolic and terpenoid compounds. We perform cluster analysis of these data and construct tree diagrams showing the grouping of investigated plants in clusters according to their microelement profile and essential oil composition. It is found that the microelement profile and the essential oil composition correlate well between each other and this correlation is in line with the conventional taxonomic classification of considered species based on their morphological characteristics. We showed that the microelement profile of a plant and the multicomponent composition of its essential oil are interrelated and species-specific.
