Abstract: Three composite sample collected from different location (White Nile, kordofan, and Khartoum) in the Sudan were subjected to GPC- MALLAS, molecular weight distribution. and emulsification analysis the result show that. The samples have Molar masses of 4.00x105 g.mol-1, – 3.7×105 g.mol-1- 3.8x105 with a radius of gyration (Rg) in the range of (25.6 – 36.6 - 66). respectively. The gum is fractioned into three fractions with different concentrations and different molar masses and different radius of gyration (Rg). The First fraction is an Arabinogalactan protein with molecular weight 3.924x105g.mol-1 and an Rg 52.2. The second and third fractions correspond to an Arabinogalactan and a glycoprotein with a total molecular weight of 3.292x105 g.mol-1 and mass recovery of 98.66%. Emulsification properties of Azadirachta indica gum were examined using droplet size technique as prepared and after accelerated stability test for 3 and 7 days at 600C. The results show emulsion droplet size, range 0.01 - 1 microns. Indicating high emulsion stability.
