Сравнительный фитохимический анализ цветков Rudbeckia hirta L. и Echinacea purpurea L.

Abstract

The botanical characteristic of Echinacea purpurea L. as the inserted species form the Republic of Belarus is given. Identification of raw Echinacea purpurea L. harvested in the territory of the Republic of Belarus is held. The alcohols extracts of Echinacea purpurea L. contained a significant amount of hydroxycinnamic acids and a few amount flavonoids. The flavonoid composition of Rudbeckia hirta L. compared with the composition of Echinacea purpurea L. flavonoids is more varied. The composition of Echinacea purpurea L. hydroxycinnamic acids is more diverse in com- parison with the composition of Rudbeckia hirta L. flowers hydroxycinnamic acids. The total content of phenolic com- pounds (flavonoids and hydroxycinnamic acids) in flowers of Echinacea purpurea L. exceeds the content of phenolic compounds (flavonoids, hydroxycinnamic acids and anthocyanins) in the flowers of Rudbeckia hirta L. more than twice.
