From the glycosidic extract of piñuela fruit; 1-O-β-D-glucopyranosyl anthranilate was isolated by adsorption chromatography on XAD-2, followed by rotation locular counter-current chromatography, multilayer coil counter-current chromatography and HPLC. Identification was carried out by NMR (1H, 13C, 1H-1H and 13C-1H COSY) and HPLC-MS/MS under electrospray ionization.
