Abstract
The fatty acids in the oil of Garcinia kola, Tetracarpodium conopodium and Tectona grandis were determined using a Perkin Elmer Auto sampler XL gas chromatograph with FID detector and split injector operating at 220ºC. The result showed that Garcina kola contained saturated fatty acid (15.78%) monounsaturated fatty acid (33.29%) and polyunsaturated fatty acid (50.92%). Tetracarpodium conopodium contained saturated fatty acid (5.72%) monounsaturated fatty acid (77.31%) and polyunsaturated fatty acid (16.96%) tectona grandis contained saturated fatty acid (59.93%), monounsaturated fatty acid (24.08%) and polyunsaturated fatty acid 15.99%. The major fatty acid in Garcinia kola is oleic acid, while the major fatty acid in Tetracarpodium conopodum is paullinic acid and the major fatty acid in Tectona gradis is palmitic acid. In conclusion, the result of the fatty acid profile showed that Tetracarpodium conopodium and Garcinia kola contained high percentage of essential fatty acids while Tectona grandis also contained some essential fatty acids. Therefore the seeds oils may be useful in the food, beverages, fine chemical, oil and pharmaceutical industries.
