Characterisation of citrus by chromatographic analysis of flavonoids

Abstract

Flavonoid glycosides in citrus were characterised by high-performance liquid chromatography using both ultraviolet and fluorescence detection. The effects of sample preparation on the chromatographic profiles are reported. Key variables in the profiles useful as chemotaxonomic markers were identified with the aid of pattern recognition, which was also used to create sample categories. LC–MS data are presented and the advantages of mass spectrometric detection are demonstrated. © 1997 SCI.
