Dynamics of accumulation of flavonoids in different organs of Sambucus nigra and S. ebulus

The article is devoted to the phytochemical study of flavonoids in various organs of species of the Sambucus L. genus. The results of studying the dynamics of accumulation of the amount of flavonoids in the composition of S. nigra and S. ebulus species depending on the phases of plant development in various organs showed that during the vegetation period the amount of flavonoids undergoes a sharp change. It was established that in the generative organs of the studied species S. nigra and S. ebulus , the maximum amount of flavonoids accumulates in flowers (7.34%, 5.58%, respectively), the minimum amount in green fruits (1.91%, 2.83%). In the vegetative organs, the maximum amount accumulates in the leaves (4.94, 4.91%), and the minimum amount in roots (0.95%, 0.67%) and stems (1.46, 1.32%). The results obtained are of practical importance, since they indicate the possibility of using various plant organs as a source of raw materials for the production of flavonoids.
