Gum Ghatti is an exudate gum from the tree Anogeissus latifolia found in India and Sri Lanka . Applications are similar to Gum Arabic in the food and pharmaceutical industries where it is used as an emulsifier.

The polysaccharide is reported to have an extremely complex structure which contains both oligosaccharides and polysaccharide elements. The polysaccharide contains Ara, Gal, Man, GlcA and Rha in a molar ratio of 61:39:6:10:6, a backbone of (1,6)-linked β-D-galactopyranosyl units and side chains of L-arabinofuranose units with some (1,4)-D-glucopyranosyluronic acid units, some joining (1,2)-D-mannopyranosyl units.

The oligosaccharides are reported to mimic the side chains and include the structures depicted below.
