Sterculia setigera is a deciduous tree species within the Malvaceae family. It commonly occurs in the Sahelo-Sudan and Guinea savannah zones of Tropical Africa. Among the Hausa people it is known as Kukkuki. [3] It is an important tree crop in Senegal as Gum karaya obtained from the woody species is exported from the country. [4] [5]

Description

A deciduous tree that is capable of reaching 18 meters in height, [6] it has an open spreading crown with buttressed base, its grey purple bark peels off in thin, irregular scales [4] leaving pale patches, while a slash reveals a fibrous, brownish to red inner bark and a white exudate.

Leaves are simple and alternate in arrangement, nerves palmately arranged at base with leaves 5 entire or pointed lobes; leaf-blade is ovate to orbicular in outline, upper surface tends to be stellate and tomentose.

Inflorescence is raceme type, calyx, 5 lobed, up to 12 mm in diameter, outer surface is green while inner surface is purple-red. The flowering period begins towards the end of the dry season between the months of February and April. [4] Fruit is a sessile follicle, 6-10 cm long, [6] oblong in shape, grey-green or brown in color and many seeded, follicle can stay on tree even when seeds falls off.

Distribution

Occurs from Senegal eastwards to Sudan and Ethiopia and in Angola, found in the savanna ecological zones, frequently on hill or rocky soils and in shallow gritty soils. [4] [6]

Chemistry

Tests on stem bark extracts of the plant isolated the chemical compound, lupeol and a class of Procyanidin trimers. [7] The sugar properties of the gum obtained from the species consisting of D-galacturonic acid, L-rhamnose, D-galactose [8] is quite similar to those obtained from Sterculia Urens . [9] [10]

Uses

Seeds are eaten by nomadic groups in Northern Nigeria. [3] A wide spread species, it has multi-purpose functions in various local communities. A decoction of stem bark extracts are used as part of an herbal regimen to treat skin ailments and infections, fever, diarrhea and toothache. [7] [11]

<span class="mw-page-title-main">Gum arabic</span> Natural gum obtained from Acacia sensu lato tree

Gum arabic is a natural gum originally consisting of the hardened sap of two species of the Acacia tree, Senegalia senegal and Vachellia seyal. However, the term "gum arabic" does not actually indicate a particular botanical source. The gum is harvested commercially from wild trees, mostly in Sudan and throughout the Sahel, from Senegal to Somalia. The name "gum Arabic" was used in the Middle East at least as early as the 9th century. Gum arabic first found its way to Europe via Arabic ports, and so retained its name.

<span class="mw-page-title-main">Gum karaya</span> Chemical compound

Gum karaya or gum sterculia, also known as Indian gum tragacanth, is a vegetable gum produced as an exudate by trees of the genus Sterculia. Chemically, gum karaya is an acid polysaccharide composed of the sugars galactose, rhamnose and galacturonic acid. It is used as a thickener and emulsifier in foods, as a laxative, and as a denture adhesive. It is also used to adulterate Gum tragacanth due to their similar physical characteristics. As a food additive it has E number E416.
