Práca sa zaoberá izoláciou a identifikáciou látok z petroléterového a metanolového extraktu holodisku dvojfarebného – Holodiscus discolor (PURSH) MAXIM., Rosaceae. Z petroléterového extraktulistov tejto rastliny bol izolovaný b-sitosterol a taraxasterol, z metanolového extraktu luteolín-7-O-glukozid. Látky boli identifikované na základe spektrálnych údajov a porovnaním s autentickýmivzorkami.

The paper deals with the isolation of constituents from light petrol and methanol extracts of theleaves of Holodiscus discolor (PURSH) MAXIM., Rosaceae. b-sitosterol and taraxasterol wereisolated from the light petrol extract, luteolin-7-O-glucoside was isolated from the methanol extract.The isolated compounds were identified by spectroscopic means and by comparison with authentic samples.
