The aim of the research was to establish efficient microclonal propagation conditions of endangered Crambe mitridatis plants in vitro and to study the possible effect of aseptic cultivation on biochemical composition (hydroxycinnamic acids, flavonoids, phenolic compounds) of plants. Methods. In vitro plant culture methods were applied. Seeds were used for aseptic culture initiation. Morphogenic potential of root, leaf and petiole explants was studied on Murashige-Skoog medium with addition of plant growth regulators. The content of biologically active compounds was measured using spectrometry in plants grown in aseptic conditions and in the greenhouse. Results. Morphogenic potential of root, leaf and petiole explants was studied and the highest regeneration frequency of plantlets was established for root explants (80 %), for petiole explants (50 %) and the lowest for leaf explants (20 %). It was found that plants cultivated in aseptic conditions have higher hydroxycinnamic acids, flavonoids and phenolic compounds compared to plants grown in vivo. Conclusions. It is advisable to multiply C. mitridatis plants in vitro via root and petiole explants. Aseptic cultivation contributes to synthesis of biologically active compounds (auxin synergists) in C. mitridatis plants.Keywords: in vitro culture, hydroxycinnamic acids, flavonoids, phenolic compounds, Crambe mіtridatis.
