ABSTRACT:
A process for preparing nitroaromatic glycosides is described. The process comprises contacting an acetylated glycoside of maltotetraose, maltopentaose or maltohexaose with a phenol, nitrating the resulting product to place a NO.sub.2 group on the aromatic moiety and deacetylating the nitrated product. The nitroaromatic glycosides are useful as standard substrates for the assay of .alpha.-amylase.
