Abstract

---

Landolphia owariensis belongs to the family Apocynaceae and its roots are commonly used as medicinal plant for the treatment of malaria and as purgative. The leaves extract is antimicrobial and the stem extract is used as a vermifuge. The phytochemical analysis of L. owariensis indicated secondary plant metabolites such as tannins, and flavonoids. The presence of tannins and flavonoids makes it imperative to conduct a formal study of its tanning potentials. This paper is reporting the application of phytochemical and classical methods of tannin analysis, and the use of the extracts for tanning purpose. The result of the phytochemical analysis showed the presence of tannins, saponins, fat and oils; while the classical analysis showed that the extract contains tans, non-tans, total soluble and moisture. The tanning extracts were used to tanned goat skins and the resultant leather shows favorable standard value for shrinkage temperature, tensile strength, and ball burst
