Abstract
Accumulation dynamics of biologically active substances (flavonols, catechins, tannins, pectin substances, saponins, and carotenoids) in the organs of aboveground parts of the plants Rheum altaicum Losinsk. growing in the experimental plot of the CSBG SB RAS (Novosibirsk, Russia) was studied. Their distribution character during vegetation period that is regrowth, budding, flowering and fruiting phases is demonstrated. The buds and flowers of plants may be a source of flavonols (7.40 and 5.89 %), catechins (0.91 and 2.01 %), tannins (32.37 and 27.83 %), and saponins (34.29 and 17.99 %, respectively), as established. Leaves in budding and flowering phases accumulate significant amounts of almost all groups of compounds, especially many carotenoids (160.05 and 191.81 mg/dL). Leaf petioles during these periods are a rich source of pectin substances (3.47 and 4.66 % of pectins, 7.22 and 9.20 % of protopectins), and saponins (24.06 and 22.3 %). Considering the findings, cultivated R. altaicum may be recommended as raw materials enriched with a complex of biologically active substances.
