ABTRACT This study examined the physico-chemical properties of acacia radiana tortilis var. Radiana from East Nile, Khartoum North. The analysis revealed a moisture content of 9.92%, a total ash value of 2.63%, a pH value of 4.3, and an absolute viscosity of 58. The specific rotation measured was-11. Cationic composition showed sodium (711.45 mg), magnesium (4.49 mg), calcium (15.17 mg), vanadium (1.79 mg), iron (2.56 mg), nickel (1.98 mg), copper (0.64 mg), arsenic (4.08 mg), aluminum (2.29 mg), and lead (4.38 mg). Glucuronic acid was extracted from acacia radiana gum using ion exchange chromatography, followed by the production of magnesium glucuronate via the addition of magnesium bicarbonate. Magnesium glucuronate properties assessed included a moisture content of 10.3%, a total ash of 1.85%, pH of 6.41, an absolute viscosity of 16.25, and a specific rotation of-6. Elemental analysis confirmed sodium (5.49 mg), magnesium (17.19 mg), calcium (71.89 mg), vanadium (1.59 mg), iron (1.45 mg), nickel (1.79 mg), copper (0.44 mg), arsenic (3.84 mg), aluminum (1.49 mg), and lead (3.93 mg). The findings supported the formulation of an antacid tablet incorporating magnesium glucuronate, leveraging its beneficial properties. In this study magnesium glucuronate was prepared from acacia tortilis var radiana , a sample of acacia tortilis collected from sherg alnile khrtoum north, and his physicochemical properties was determined. Glucoronic acid was prepared by using ion exchange chromatographic technique then magnesium glucuronate was prepared by adding magnesium bicarbonate. Physicochemical characterization of magnesium glucuronate gave moisture content was 10.3%, total ash 1.85%, pH value 6.41, absolute viscosity 16.25 Cp, specific rotation +44,and cationic composition was Na=5.49, Mg= 17.19, Ca = 71.89, V= 1.59, Fe = 1.45, Ni = 1.79, Cu = 0.44, As =3.84, Al = 1.49, Pb = 3.93 ml\l.
