title: [Flavonoids - main constituents of the leaves of Philadelphus tenuifolius Rupr. et Maxim].
abstract: The paper deals with the isolation and identification of the constituents of the leaves of Philadelphus tenuifolius Rupr. et Maxim. A methanolic extract was used to isolate quercetin-3-O-glucoside (isoquercitrin), and a butanolic extract to isolate kaempferol-3-O-glucoside-7-O-rhamnoside. Isolates were identified by physical-chemical data, comparison with authentic samples and literature data. The above-mentioned compounds were isolated from Philadelphus tenuifolius Rupr. et Maxim. for the first time.
