ABSTRACT
Elemental analysis is the qualitative detection and quantitative determination of chemical elements(atoms,ions)in a sample(Fritz Pregl 1923). To detect an ix element, one should fix an appearance of an analytical signal. The formation of precipitate or characteristic crystals, colour change, an isolation of gaseous products, an appearance of a definite lines in spectrum, luminescence, etc. To determine elements quantity, it is necessary to measure a value of an analytical signal; a precipitate mass, intensity of a current, solution absorption, spectrum line, luminescence or radioactivity, a reaction rate and so on.(www.intechopen.com). This study was undertaken to analse the elements present in grounded Pterocarpus mildbreadii (Oha seed) using Atomic Absorption Spectrometer(AAS MODELAA320N).The seed was found to contain these essential macro minerals/elements sodium(Na),Potassium(K),calcium(Ca),magnesium(Mg),and the trace elements iron(Fe),copper(Cu),zinc(Zn), and selenium(Se)(Duffus,2002). The study established that Pterocarpus mildbreadii(oha seed) does not contain manganese and has high content of potassium which is necessary for good health.
