Key Word Index - Citrus paradisi; Rutaceae; grapefruit; biotransformation; glucosylation; plant cell cultures; flavanones; flavanone glycosides; prunin; hesperitin 7-O-glucoside; 1H NMR.Grapefruit (Citrus paradisi) cells in suspension cultures did not accumulate flavanone glycosides but were able to specifically O-glucosylate exogenous naringenin and hesperitin at position 7.The products were extracted from the cultures using a new technique: absorption on an Amberlite XAD-2 resin and further purification by BioGel-P4 column chromatography.The flavanone glycosides obtained were analyzed by high-resolution 1H NMR and the spectra compared to authentic flavanone aglycones, mono- and diglycosides.
