Guill. & Perr. (Combretaceae) 2018-09-10T04:43:14+00:00 Muzamil Hassaballa A. El-Mula Elfatih A. Hassan Mohamed E. Osman <p><em>Anogeissus leiocarpus</em> gum samples were collected as natural exudates from different locations of gum belt in Sudan, the physico<a href=";cat=&amp;ascicat=ALL&amp;Submit=Search&amp;keyword=chemical+properties">chemical properties</a> of the gum were studied, the solubility of this gum was 14.5% w/v dissolves in water at 25<sup>o </sup>C to form a clear solution, moisture content range between (6.987% to 8.649% w/w), ash content between (2.00% to 2.05% w/w), pH between (4.39 to 4.65), refractive index between (1.58 to 1.60) , nitrogen between (0.125% to 0.155%), protein between (0.81% to 1.00%), specific optical rotation between (-33.8 to -35.2). The cationic composition was in the order: (Ca<sup>++</sup>) 4533 ppm has the highest value in all samples followed by (K<sup>+</sup>) 3520 ppm, (Mg<sup>++</sup>) 1047 ppm, (Na<sup>+</sup>) 600 ppm, (Fe<sup>++</sup>) 562 ppm , (Pb<sup>++</sup>) 258 ppm, (Zn<sup>++</sup>) 197 ppm and trace amount of (Mn<sup>++</sup>) 74.5 ppm, (Cr<sup>++</sup>) 4.5 ppm. Intrinsic viscosity was 0.115 in NaCl and 0.914 in H<sub>2</sub>O, reducing sugar as follows; Rhamnose was 9.288%, Aribanose was 34.00%, and Galactose was 27.50%, estimation of equivalent weight was 1384.33 and uronic acid 14.02. The analysis of variance showed insignificant differences (p&lt;0.05) in all properties studied.</p> <div class="SnapLinksContainer" style="margin-left: 0px; margin-top: 0px; display: none;"> <div class="SL_SelectionRect">&nbsp;</div> <!-- Used for easily cloning the properly namespaced rect --></div> 2018-06-30T00:00:00+00:00 ##submission.copyrightStatement##
