摘要：

The liberation of nitrophenol from eleven nitrophenyl glycosides in acid or neutral solution in the presence of l-ascorbic acid is reported. The conditions under which o-nitrophenol β-d-galactopyranoside are reported. The reaction rate, which is proportional to temperature and glycoside concentration, is maximal between pH 4 and 5, but negligible above pH 8.5, and is increased by Cu2+. At low concentrations of l-ascorbic acid the reaction rate is proportional to l-ascorbic acid concentration, but at higher concentrations the reaction rate is not further increased. Other monosaccharides inhibit the release of nitrophenol. © 1968.
