Structural characterization of flavonoid glycosides by multi‐stage mass spectrometry

Abstract: Flavonoids are secondary plant metabolites of great structural variety and high medicinal significance. The search for new chemical entities and the quality control of flavonoid containing natural products require easy-to-use but reliable and robust analytical methodologies. For structural elucidation of flavonoids and their glycosides, nuclear magnetic resonance (NMR) and mass spectroscopy (MS) are the generally used techniques. In phytochemical analyses, however, high amounts of flavonoids are difficult to i… Show more

“…The sugar type can be easily determined by the characteristic m/z values of the A i , fragments arising from hexoses, which are not directly observable in the mass spectra but can be computed from the m/z differences of the parent ions and corresponding X i [13,15,16].…”
