Kaempferol-3-O-[6^Glc-O-feruloyl]-β-d-glucopyranosyl-(12)-O-[α-l-rhamnopyranosyl-(16)]-β-d-galactopyranoside (1) was isolated from the aerial parts of Brunfelsia grandiflora ssp. grandiflora. The structure of this novel flavonol glycoside was established by fast atom bombardment-mass spectrometry and by means of NMR spectroscopy at 14T, using two-dimensional NMR experiments with pulsed-field gradients for coherence selection. The presence of the constituent aglycones and sugar units of 1 was confirmed independently by acid hydrolysis.
