Abstract
In this research from Azadirachta Indica (Wild) , neem gum was
fractionated by foaming method into two fractions, high protein
fraction (HPF) that represents 65% of the weight gum and a low
protein fraction (LPF) which represents 35% of the gum.
A comparative study between the crude gum and the two
fractions was conducted in the scope of their physiochemical
properties.
Proximate analysis of the crude gum and fractions HPF and LPF
respectively revealed that, the moisture content 7.56 and 7.54,
ash% 8.41and 8.31 .The nitrogen 1.41 and 1.31and the protein
content 2.85, 0.91 ,specific rotation +57.8and +55.8, the pH 4.5
and 4.3, equivalent weight and molecular weight of the neem
gum in two fractions HPF and LPF respectively revealed that
(equivalent weight = 4.87 x 105 and 4.57 x 105; molecular
weight = 7.31 x 105 and 7.01 x 105 were insignificantly
different.
However the intrinsic viscosity of the Fraction was 17.6 and 6.6 cm-3/g were highly significantly different.
