Abstract
Flavonoid content was studied in the organs of the top part of plants of seven species of Hedysarum L. genus (H. alpinum L., H. flavescens Regel et Schmalh., H. austrosibiricum B. Fedtsch H. neglectum Ledeb., H. theinum Krasnob., H. gmelinii Ledeb. и H. tschuense A. I. Pjak et A. L. Ebel) growing in the forest-steppe zone of West Siberia (Novosibirsk) and in natural populations in the Republic of Altay and Northern Kazakhstan. The species peculiarity of the accumulation of flavonoids was observed: the largest amount of flavonoids was detected in the leaves of H. flavescens, H. alpinum and H. theinum species (up to 15.0, 13.2 and 11.1 %, respectively). In general, all the studied species of Gamotion section are distinguished by exclusively high flavonoid content independently of age. The representatives of Multicaulia section H. gmelinii and H. tschuense are distinguished by somewhat lower (in comparison with the above-indicated species) flavonoid content (2.6 and 1.8 %, respectively). The species of Gamotion section are to be recommended as the source of flavonoids because the introduced and wild plants are characterized by the exclusive ability to synthesize the large amount of these compounds.
