The paper deals with the isolation and identification of constituents of the leaves of Holodiscus discolor (Pursh) Maxim. (Rosaceae). Three flavonoid glycosides of flavonol type were isolated from the methanolic extract: kaempferol–3–O–rhamnoside, quercetin–3–O–glucoside (isoquercitrin) and quercetin–3–O–rhamnoside (quercitrin). Isolates were identified by physical-chemical data, by comparison with authentic samples and literature data. The above-mentioned compounds were isolated from Holodiscus discolor (Pursh) Maxim. for the first time.
