Abstract:
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. © 1986.
