Flavonoid composition of the leaves of Spiraea media var. media Schmidt (7 populations) and S. media var. sericea (Turcz.) Regel (2 populations) were studied. Contents of quercetin, kaempferol and isorhamnetin in hydrolysates were determined, and quercetin, kaempferol, hyperoside, isoquercitrin, rutin, avicularin, astragalin, isorhamnetin 3-rutinoside in extracts were done. Largest number of flavonoid compounds was found in extracts of S. media var. media from natural population in the Olyokminsky district in the Yakutia (33 compounds), its smallest number was found in the extracts of S. media var. sericea from the Olginsky district in the Primorsky Krai (18 compounds). Populations of S. media var. media differ in the predominant constituents. In its permanent constituents 12 flavonol glycosides were revealed, including hyperoside, astragalin and isorhamnetin 3-rutinoside. Specific constituents for S. media var. sericea were not found, in its permanent constituents 14 flavonol glycosides were revealed, including hyperoside, isoquercitrin and avicularin. The absence of isorhamnetin glycosides in the leaves of S. media var. sericea from the Olginsky district in the Primorsky Krai is indicated the possible membership of similar populations of separate species S. sericea.

Key words: Spiraea media var. media, S. media var. sericea, flavonols, quercetin, kaempferol, isorhamnetin, rutin, hyperoside, astragalin, avicularin, isoquercitrin, isorhamnetin 3-rutinoside.
