Anodyne  Antiarthritic  Antirheumatic  Febrifuge  Kidney  Ophthalmic  Parasiticide

The bark is used in traditional medicine[ 299 ]. A decoction is drunk to treat fever[ 299 ]. The bark is also used, usually in external applications, as an anodyne against stomach-ache and peptic ulcers, earache, and kidney, rheumatic or arthritic pains[ 299 ]. It is also applied externally to treat ophthalmia, swellings and ulcers[ 299 ]. Methanol extracts of the bark have shown dose-dependent inhibitory effects on gastric ulcers[ 299 ]. The triterpenoid methyl angolensate, isolated from the bark, exerted inhibition of gastric ulceration and smooth muscle activity, and reduced the propulsive action of the gastrointestinal tract[ 299 ]. Methyl angolensate has shown sedative activity[ 299 ]. Bark extracts have shown moderate antiplasmodial activity; the compounds 7_-obacunylacetate and 24-methylenecycloartenol exhibited pronounced activity against chloroquine-resistant strains of Plasmodium falciparum[ 299 ]. Tirucallane triterpenes have been isolated from a leaf extract[ 299 ].

Charcoal  Containers  Dye  Fuel  Parasiticide  Wood

Agroforestry Uses: The tree is planted as roadside tree, and occasionally as a shade tree in banana, coffee and tea plantations[ 299 ]. Other Uses: Shavings of the wood, combined with rice husks, have been processed in a pressure vessel in the presence of aqueous sodium sulphide to produce a brilliant yellow dye of reasonable fastness to light and alkaline wash on cotton fabrics[ 299 ]. The heartwood is pale pinkish brown to pale reddish brown, slightly darkening upon exposure to deep reddish brown, with golden shades; it is distinctly demarcated from the 6 - 10cm wide band of creamy white to pale pinkish sapwood. The grain is interlocked, texture moderately coarse and fairly even. The wood is light in weight; moderately soft; moderately durable, being resistant to dry wood borers, liable to powder-post beetle, pinhole borer and marine borer attacks and with variable resistance to termites. It air dries somewhat slowly, with a high risk of checking and distortion; once dry it is moderately stable to stable in service. The wood saws and works easily with both hand and machine tools; it has only moderate blunting effects on cutting edges. Drilling, mortising and turning properties are all satisfactory. The wood is not liable to splitting in nailing and screwing, with good holding properties. The gluing, staining and polishing properties are good, but the steam bending properties are poor. The wood is suitable for veneer production. The wood is highly valued for exterior and interior joinery, furniture, cabinet work, veneer and plywood, and is also used for flooring, interior trim, panelling, stairs, ship building, vehicle bodies and coffins. It is suitable for light construction, musical instruments, toys, novelties, boxes, crates, carvings and turnery[ 299 , 848 ]. Wood that is not suitable as timber is used as firewood and for charcoal production[ 299 ]. The seeds have a fat content of about 60%. The fat is rich in cis-vaccenic acid, an oleic acid isomer that can be used in the industrial production of nylon-11. The approximate fatty acid composition of samples of the oil from Ghana and Nigeria is: palmitic acid 4 - 6%, palmitoleic acid 11 - 16%, hexadecadienoic acid 3 - 5%, stearic acid 10 - 15%, oleic acid 2 - 3%, vaccenic acid 32 - 43%, linoleic acid 11 - 15% and arachidic acid 1 - 2%. Tests with tadpoles showed that the seeds contain toxic compounds, probably limonoids.
