Abstract
Nine flavonoid glycosides were isolated from birch leaves by preparati ve HPLC and their structures identified by chromatographic (analytical HPLC), chemical (hydrolysis) and spectroscopic (UV, NMR, MS) techniqu es. Two acylated compounds: myricetin-3-O-alpha-L-(acetyl)-rhamnopyran oside and rcetin-3-O-alpha-L-(4''-O-acetyl)-rhamnopyranoside were foun d in birch leaves for the first time. Flavonoid concentrations were qu antified by HPLC.
