Abstract

Phenolic compounds in closely related taxa Filipendula ulmaria , F. denudata and F. stepposa were studied by HPLC and spectrophotometry. The main flavonols of leaves are hyperoside and isoquercitrin. In F. ulmaria and F. denudata , in addition, significant quantities of ellagic acid and avicularin are present, and in leaves of F. stepposa - astragalin. No signifi cant differences were found between F. ulmaria and F. denudata on the qualitative composition and quantitative content of phenolic compounds in the leaves. In the leaves of F. stepposa glycoside avicularin which is the major component at the first two taxa was not found. The study of phenolic compounds of Filipendula confirms the data of morphological studies: there are no obvious differences between the F. ulmaria and F. denudata , but visible isolation of F. stepposa from these two taxa is observed. In the conditions of the culture in the botanical garden of UB RAS observed reduction of the amount of flavonols and tannins at infl orescences compared to natural conditions.
