At least 22 phenolic compounds were identified in aqueous-ethanol extracts from Sorbaria pallasii (G. Don fil.) Pojark. leaves and at least 28 in its inflorescences by High-Performance Liquid Chromatography. Two acids (chlorogenic and p-hydroxybenzoic) and five flavonols (hyperoside, isoquercitrin, quercitrin, kaempferol, and astragalin) were identified among them. Flavonoid aglycones were obtained from the leaves and inflorescences by hydrochloric-acid hydrolysis of the aqueous-ethanol extracts (1:1). Three flavonol aglycones (quercetin, kaempferol, and isorhamnetin) were identified in the extract hydrolysates from S. pallasii above-ground organs through chromatographic analysis. Additionally, a flavone aglycone (luteolin) was found in the extract hydrolysates from the leaves. Kaempferol glycosides are predominant phenolic compounds in S. pallasii inflorescences, and quercetin glycosides in its leaves.
