High-performance liquid chromatography of flavonoids in Crataegus oxyacantha L. IV. Reversed-phase high-pressure liquid chromatography in flower, leaf and bud extractives of Crataegus oxyacantha L.
RP-HPLC has been used for qualitative and quantitative analysis of some flavonoids in flowers, leaves and bud extracts of Crataegus oxyacantha L. Peak identification was obtained by comparison with retention times of pure standard substances and by UV analysis. Luteolin, luteolin-3', 7-diglucoside, apigenin, apigenin-7-O-glucoside and rutin have been identified and determined.
