Phytochemical composition of Heracleum sibiricum plant organs growing on the territory of Kuzbass
The quantitative phytochemical composition of the aboveground and underground organs of a plant growing in the Kemerovo region, Siberian hogweed (Heracleum sibiricum), was studied in order to use the invasive species as new sources of biologically active substances with an immunomodulatory effect. The objects of the study were the foliage, roots, and inflorescences of Heracleum sibiricum harvested during the growing season of 2023. Quantitative determination of tocopherols was carried out by HPLC with fluorimetric detection. Analysis of the content of flavonoids, anthocyanins, and betacyanins was carried out on a chromatograph with a diode array detector and a fluorometric detector. Phytomelanins were isolated according to the method of L.A. Ivanova et al. using alkaline extraction. Analysis of the content of micro- and macroelement composition was carried out under conditions of atomic emission spectroscopy with inductively coupled plasma. The highest content of tocopherols was recorded in the inflorescences collected in July – 55.6 mg/100 g. Leaves collected in July 2023 have a high content of flavonoids – 2.3 g/100 g. Analysis of the pigment composition showed that anthocyanins are mainly contained in inflorescences, and betacyanins – in leaves. The maximum content of water-soluble phytomelanins was also observed in inflorescences. According to the results of the study of macro- and microelement composition, the highest amount of macroelements (Ca, Mg, Na, P and S) is observed in the leaves collected in June. The highest amount of potassium was recorded in the stems collected in July. Leaves collected in June have the highest content of microelements, such as Al, B, Ba, Cu, Fe, Li, Mn, Mo, Si, Sr, Ti, and Zn. The highest amount of Ba, Be, Cr was recorded in the stems collected in July. Nickel was found in the inflorescences collected during the same period. Thus, the choice of plant organ and time of its collection depends on the specific biologically active substance and its further application.
