Abstract

This study compared the phytochemicals, composition, and trace elements of Mangifera indica leaves with a control sample. Seven phytochemicals were found in the methanolic extract of Mangifera indica leaves, while eight were found in the control. Tannery effluent is an environmental pollutant that can be harmful to ecosystems. Alkaloids, saponins, tannins, phenols, and quinone were present, while oxalate, steroids and reducing sugar were absent for both Mangifera indica leaves methanolic extract and control sample. Glycoside and phlobatanins were present in Mangifera indica leaves methanolic extract while absent in the control sample. Anthraquinone, resin and flavonoid were absent in Mangifera indica leaves methanolic extract but present in the control sample. The percentage composition for proximate analysis of the Mangifera indica leaves for moisture content, ash content and crude fats were 7.3%, 6.4% and 6.48%, respectively. The control percentage composition for moisture content was 8.0%, ash content was 6.3%, and crude fats were 9.32%. The percentage composition of alkaloid, saponin and lipids in the Mangifera indica leaves was 10.01 %, 9.66% and 3.66%, respectively. The control percentage composition of phytochemicals was alkaloid, 11.1%., saponin, 9.88% and crude lipids, 4.22%. Copper detected in the Mangifera indica leaves was 0.04384 mg/l while 0.00525 mg/l for control. Lead was found in Mangifera indica leaves at 0.0011 mg/l but not in the control sample. Cadmium was not detected in either sample. Further investigation is needed on other parts of the plant.
