Background and Objective: Plants contain immensurable biologically bioactive ingredients that enabled them tobeuse as medicine. This study aimed to provide information on the phytochemicals and antioxidant present in Tetrapluera tetraptera and thus standardize and validate its use in traditional medicine in the study area.

Methods: Matured pods and the leaves of T. tetraptera were obtained and pulverized. Phytochemical tests were then carried out on portions of the powdered samples using standard procedures to estimate the quantity of secondary metabolites in the samples. Proximate analyses were carried out to determine the moisture, ash, lipid, protein, fiber and carbohydrate contents of the pulp. Similarly, the mineral compositions of the samples were determined.

Results: Phytochemical screening of the plant revealed that it contains various bioactive constituents that enabled it function as medicine. These include alkaloids, saponins, flavonoids, glycosides, carotenoids, phenol and antioxidant. The fruit has higher antioxidant capacity than the leaf. Proximate analyses revealed the presence of crude fibres, proteins, fats, carbohydrates, ash and moisture contents in the plant. The determination of the mineral composition showed that the different elements present were more in the leaves than the fruits.

Conclusion: This study demonstrated that the species contained varying amounts of phytochemicals and nutrients that justified its medicinal use by the aborigines of the study area. Thus the species is promising as a source of raw material for a wide range of applications in the food and drug industries.
