The glycoside of 4-nitrocatechol with β-D-galactopyranose was prepared by the glycosylation of this phenol as sodium phenoxide with tetra-O-benzoyl-α-D-galactopyranosyl bromide. The structure of the reaction products was confirmed by 1H and 13C NMR spectra and by chemical analysis. The latter consisted of acidic hydrolysis, followed by ethyl ether extraction and colorimetric determination of 4-nitrocatechol in the ether phase and application of the anthrone method for the sugar in the water phase. The synthetic glycosides were tested as substrates for enzymes from animal, vegetal, and microbial materials.</dcterms:abstract> <dc:contributor>Iga, Silvia</dc:contributor> <dc:contributor>Duica, Florentina</dc:contributor> <dc:contributor>Schmidt, Richard</dc:contributor> <dc:contributor>Hotoleanu, Corina Loredana</dc:contributor> </rdf:Description> </rdf:RDF>
