Seventeen natural C‐glycosylflavones have been analysed using positive desorption chemical ionization mass spectrometry with ammonia as reagent gas. This technique provides the molecular weight, information for the identification of the aglycone, the sugar sequence, and the characterization of the C‐sugar (hexose, pentose). The distinction between mono‐C‐glycosylflavones, di‐C‐glycosylflavones, C‐glycosylflavone 2″‐O‐glycosides, and di‐C‐glycosylflavone 2‴‐O‐glycosides is also obtained.
