An analytical study has been made of six gum specimens from Albizia le
bbeck, Leguminosae. Galactose, mannose, arabinose, glucuronic acid and
its 4-O-alpha-methyl analogue are present in all the specimens studie
d. Rhamnose was not detected according to sugar analysis and spectral
data. The absence of this sugar, the high acidity and the relatively l
ow limit viscosity number contrast with the values reported previously
for one African sample of A. lebbeck. The lead content is much higher
than that recorded for other Albizia gums. C-13-NMR spectrum of this
gum, in deuterium oxide, shows good resolution.
