ABSTRACT
This thesis presents the results of an experiment aimed at investigating the metallic composition of Picralima nitida extracts in both aqueous and ethanol solvents. Picralima nitida, a plant species with known medicinal properties, was chosen for its potential metal accumulation properties. The metal composition analysis showed the presence of various essential and nonessential elements, with sodium, potassium, and iron having the highest concentrations .The experiment successfully revealed the presence of these metals in both aqueous and ethanol extracts, with potassium, calcium, and iron exhibiting higher composition compared to sodium. The analysis was carried out using advanced analytical techniques such as atomic absorption spectroscopy and inductively coupled plasma mass spectrometry, ensuring precision and accuracy. The findings of this research have significant implications for the potential use of Picralima nitida in various applications, such as herbal medicine and phytoremediation. This study contributes to the understanding of the metal content in this plant species and highlights the importance of solvent choice in extracting metals from plant materials. Further research is warranted to explore the bioavailability and bioaccumulation of these metals in Picralima nitida and their potential effects on human health and the environment.
