Abstract

The aim of the research was to examine Cola nitida and Cola acuminata for their phytochemical and proximate compositions. Presence of secondary metabolites do provide information about the plants for their potentials as a lead candidates for the novel drug discovery. The proximate analysis was done using the method of Association of Official Analytical Chemists (AOAC) and the phytochemical analysis was done using methods of Markkar and Goodchild for tannin, Brunner for saponin, Harbone for alkaloid and Bohm and Koupai-Abyazani for flavonoid. The proximate results showed that the moisture content of Cola acuminata and Cola nitida were in the range of 9.73-9.81%, ash 2.72-2.21%, fat 3.02-2.20%, protein 19.14-15.24%, crude fiber 7.30-4.18% and carbohydrate 58.09 66.45%. Cola acuminate has more protein content, ash and fat than Cola nitida. The result of phytochemical analysis showed that Cola acuminata has more alkaloids (2.22%), tannin (6.46%) and saponin (8.06%) than Cola nitida. The phenol contents of the two kola nuts were the same range 0.27%, the flavonoid were in the range of 0.12-0.14%. The presence of secondary metabolites in these plants are indications that if well researched, novel bioactive compounds can be discovered in them as there are worldwide efforts by scientists looking for new bioactive compounds to combat various ailments which have developed high resistant to already known antibiotics.
