Preparation and Physicochemical Characterization of Magnesium Glucuronate from Acacia tortilis Subspecia randiana gum

Abstract

In this study anti acid tablet was formulated from Acacia tortills var raddiana gum. Glucuronic acid was prepared by ion exchange chromatography, then magnesium glucuronate was prepared by adding magnesium bicarbonate to the eluate. Physicochemical characterization of acacia tortills var raddiana and magnesium glucuronate show the moisture content of gum sample was 9.92% and for magnesium glucuronate was 10.3%, the total ash and inorganic content of magnesium glucuronate 1.85% which is less than in gum sample, the gum sample is dextrorotatory when the magnesium glucuronate is levorotatory, the viscosity of magnesium glucuronate is slightly lower than gum’s viscosity. The gum sample is moderately acidic, when the magnesium glucuronate neutral, and mineral composition of gum sample and magnesium glucuronate show the major cations are Na, Mg, and Ca, all minerals values decreased in magnesium glucuronate in compared with gum sample except Mg and Ca which are increased.
