The aim of the study was quantitative and qualitative analysis of essential oil from underground organs (rhizomes with roots) and aboveground organs (basal and stem leaves) of Rhaponticum carthamoides plants cultivated in Polish climatic conditions. Both underground organs and leaves of R. carthamoides were characterized by low content of essential oil (0.07-0.11%). The content of essential oil in underground organs of 2-year-old plants was slightly higher than in those of 3-year-old plants. The dominant constituents of essential oil, both from underground organs and leaves appeared to be geraniol and β-caryophyllene. Relatively high percentage of linalool was also observed. There were no clear differences in the composition of essential oils from 2- and 3- year-old plants.

The content and chemical composition of phenolic compounds in above- and underground organs of dropwort during second year of plant vegetation were studied. Five flavonoids (hyperosid, astragalin, spireaoside, kaempferol, quercetin), 2 catechin derivatives ((+)-catechin, (-)-epigallocatechin), and 7 polyphenolic acids (ellagic, gallic, syringic, salicylic, chlorogenic, caffeic and rosmarinic) were identified in aboveground organs. Their content, both in flowers and leaves, was significantly higher at the beginning of flowering as compared with full flowering stage. In underground organs (+)-catechin and its derivatives ((-)-epigallocatechin, (-)-epigallocatechin gallate, (-)-epicatechin) as well as 2 polyphenolic acids (ellagic and gallic) were identified. Their content was not closely related to the stage of plant development.

The aim of present paper was quantitative evaluation of triterpenoid saponins – oleanosides occurring in leaves, inflorescences and rhizomes of annual and biennial Silphium perfoliatum L. plants. It was found that all studied above and underground organs contained triterpene saponins whose aglycone was oleanolic acid. It was proven that leaves of Silphium perfoliatum L. contained the highest amount of oleanosides as compared to inflorescences and rhizomes and thus they could be an attractive source for pharmaceutical industry. It was also found that oleanoside level in leaves decreased along with the plant’s development.
