Phytochemical Screening and Mineral Potentials of the Kernel of Dacryodes klaineana (Pierre) H.J.Lam
The importance of plant to human life is imperious, ranging from being used as food as well as shelter. There is a correlation between traditional uses of a plant and its activity in biological screening system. Dacryodes klaineana (DK) is a woody evergreen perennial with edible fruits in the family Buseraseae, which are widely applied in traditional folk medicine to treat painful menstruation, enema, cough and skin diseases. The aim of this is study was to determine the chemical and elemental composition of DK that are responsible for its activities as previously mentioned in its folkloric uses. Phytochemical screening and Mineral element composition of Dacryodes klaineana kernel was carried out using standard methods. Phytochemical screening result investigated showed that the kernel possessed some secondary metabolites which include tannins, flavonoids, alkaloids and cardiac glycosides. Despite saponins, free and combined anthraquinone being absent the presence of these secondary metabolites give credence to the fact that the seed kernel possess medicinal properties. Results obtained in the mineral analysis indicated the presence of some micro and macro nutrients such as Potassium (K), Calcium (Ca), Iron (Fe), Zinc (Zn) among others, are within the acceptable health range. The health benefits of these elements and phytochemicals cannot be ruled out, which makes DK an excellent source of minerals and secondary metabolites that should be embraced by nutraceutical and pharmaceutical industries.
