Dynamics of the Accumulation of Flavonoids in Polygonum L. Species

There are 300 species of Polygonum L. genus of Polygonaceae Juss. family in the temperate zone of the
world. Some of them are medicinal lants, which are used for the treatment of diseases or as a raw
material for preparing medicines. Flavanoids are active substances of the species belonging to the
Polygonum L. genus. Flavonoid content, distribution, dynamics of accumulation throughout growth
phases, productivity of above-ground parts have been studied in various organs of P. aviculare and P.
patulum L. species. Uneven distribution of flavonoids was detected in plant organs. In generative
organs maximum accumulation of flavonoids was observed in buds, while in vegetative organs it was
observed in leaves. Maximum biomass productivity and flavonoid content were observed in the
flowering phase of both species.
