Ukponmwan D. O.
The bark of this plant, Bosqueia angolensis was collected, dried, ground and the dyestuff extracted using absolute ethanol as solvent. The yield %, melting point, R f value and the Uv/visible absorptions of the dyestuff were determined. The dye solution prepared was used to dye some textile fabrics with and without mordants. Also, the dyestuff was used to colour some cosmetics (Petroleum Jelly). The dyed fabrics showed moderate wash and light fastness properties which improved with mordanting
