  • Title: Qualitative and quantitative chromatographic investigation of flavonoids in Pyrus communis L. flowers.
    Author: Rychlińska I, Gudej J.
    Journal: Acta Pol Pharm; 2003; 60(1):81-5. PubMed ID: 12848372.
    Abstract:
    The qualitative and quantitative analysis of flavonoids, and the quantitative determination of procyanidins in the flowers of naturally growing Pyrus communis and in the flowers of cultivated varieties were carried out. The flavonoid compounds were investigated by chromatographic methods. The flavonoid samples were found in all the studied plant materials. The content of flavonoids was determined by the Christ-Müller's and HPLC methods after acid hydrolysis. The quantitative determination of procyanidins was carried out by the spectrophotometric method.
