Abstract:
Background and Objective: Plant based oils play critical roles in human and animal nutrition, therefore making the search of plant oils with nutritional potentials unending. The study compared the chemical properties of two coconut species and characterized the fatty acid present in their oils. Materials and Methods: Oil extraction from dried coconut copra was obtained using soxhlet extractor and n-hexane as solvent. Phytochemical screening, proximate analysis of copra and physiochemical analysis of oil and all assays were carried out using standard protocol. The fatty acid composition of the oil was evaluated using gas chromatographic techniques. Results: Results showed that the copra of both species is rich in fat, carbohydrate and has high energy value. Phytochemical screening showed that phenols and saponins are more in tall, while alkaloids more in the short. Saponification value and free fatty acids values were high in the short. Fatty acid profiling showed the presence of caprylic (7.51, 6.17), capric (4.97, 4.71), lauric (50.37, 52.63), myristic (17.94, 19.65), palmitic (5.87, 8.96) and stearic (3.41, 7.82) acid in both oils (tall and short), respectively. Conclusion: From the findings of the study, it can be concluded that the coconut oil has nutritional potential and contains medium chain fatty acids, although more fatty acids were present in the tall specie.
