Glucuronic Acid Determination in Acacia Gums

Abstract

Acacia senegal, Acacia seyal and Acacia nilotica gums authentic samples were collected from various areas in Sudan representing a wide range of the natural distribution of these species in the country, namely from states of Blue Nile, Khartoum, Sinnar, and Northern Kordofan. Composite samples were prepared by mixing equal weights from each sample, taken from each location. Glucuronic acid was determined using the carbazole UV method; the results have indicated that A. seyal contains 13.00% glucuronic acid among its contents, with a deviation of 0.21% from the average values cited in previous studies. A.senegal recorded 16.00% glucuronic acid content with a 0.51% deviation from the average values published results, while A. nilotica recorded 10.21% of the glucuronic acid deviating only 0.26% from the average values obtained in by other research workers.
