Abstract

Medicinal plants are rich sources of active ingredients used in drugs synthesis and development. Monkey kola is a common name given to some edible wild relatives of West African kola nut. In this study, the physico-chemical and phytochemical profile of Cola Lepidota (monkey kola) were assessed using standard chemical methods. The proximate analysis showed that the seed contained moisture (9.40±0.02 %), ash (4.57±0.03 %), fibre (4.58±0.01 %), fat (16.70±0.02 %), protein (23.78±0.04 %), and carbohydrate (40.97±0.05 %). The Fourier transform infra- red (FTIR) spectrometer analysis revealed the presence of functional groups like Hydroxyl (-OH), Nitrile (C-N) and carboxylic acid (COOH) in the seed. Micro PIXE/RBS analysis carried on the seed revealed the presence of elements like sodium, magnesium, aluminum, silicone, phosphorus, sulphur, chlorine, potassium, calcium, manganese, iron, zinc, bromine. The percentage compositions of carbon was 57.53%, oxygen 39.96% and nitrogen 0.84%, signifying that the cola is a good source of carbon. The phytochemical contents (mg/100g) obtained in the sample were as follows; Alkaloids 4239.37±0.29, Flavonoids 10.72±0.14, Saponins 22.50±0.02, Tannins 288.44±27.00 and Terpenoids 1032.00±41.70. This result shows that Cola Lepidota (monkey kola) has some medicinal values and contains essential elements needed for human body growth and development.
