Abstract

Isolation and characterization of the main organic component of a black indigenous mineral dye;  Yombotumtum (YT) was carried out.  The methods employed include physicochemical characterization using solubility test, melting point, combustion test, organic and inorganic (ash) contents, functional group tests, IR and UV- VIS spectroscopic analysis and preparation of derivatives. The results obtained were compared with similar results when a synthetic organic compound reference was used.

Keywords: Indigenous, mineral dye, organic components, physicochemical characterization and Spectroscopic analysis.
