Successive Ethanol Fractionation of the Gum from Acacia seyal Var.seyal And Their Physio-chemical Properties

Abstract

Acacia SeyalvarSeyal gum was fractionated by precipitation using ethanol, the total percent yield was 87%.The phesio-chemical properties were determined for the gum and its fractions . The results showedthat, the moisture was (9.16)% for Talha sample and in ranges from (4.63-6.41)% for fractions , the total ash of Talha gum and its fractions were between (3.18-3.62)% , the results of optical rotation were (45-50) , the intrinsic viscosity values were (9.82-13.30)cm3/g , PH (4.62-5.95) , the protein content was calculated using coefficient factor 6.6 , it found in the rang (1.32-2.72)% .
