A preliminary study showed the presence of gluocovanillin and other glucosides in green vanilla beans ( Vanilla fragrans Andrews). The glucosides of vanillin, vanillic acid, ρ‐hydroxybenzaldehyde and ρ‐hydroxybenzoic acid have now been synthesized and their structures confirmed by mass spectrometry and 13 C‐NMR spectroscopy. A reversed phase (C‐18) HPLC method, using a photodiode array detector, enabled separation and characterization of the authentic substances and this method was applied to the determination of these glucosides in green vanilla bean extracts of various origin.
