Tithonia diversifolia, Phytochemicals, Minerals, Heavy metals, Proximate


In recent times, medicinal plants are being greatly used ethnomedicinally for the management and treatment of diseases and health conditions. One of such medicinal plants is Tithonia diversifolia. This study aimed at determining the phytochemical, elemental and proximate content of the powdered plant part to help infer what is responsible for the reported therapeutic characteristics of the plant as well as determine the quality, purity and safety profile of the plant. Leaves of T.diversifolia were subjected to phytochemical, proximate and mineral screening using standard laboratory procedures. Qualitative phytochemical observation revealed the presence of Tannins, saponins, flavonoids and terpenoids. Crude Protein content was the highest with 27.69% followed by Crude Fibre (14.89%), Ash (13.86%), Moisture Content (10.92%) and the least value 1.14% for Fat. Magnesium (Mg) content was highest with 6712.50mg/kg which is 22, 35, 122 & 144 times higher than the content of Iron (Fe) (291.5mg/kg), Manganese (Mn) (191.0mg/kg), Zinc (Zn) (54.9mg/kg) and Copper (Cu) (15.1mg/kg). However, elements (heavy metals) Lead (Pb), Cadmium (Cd), Chromium (Cr) and Cobalt (Co) were not detected. Results obtained in the study is indicative of a potential drug substitute which can be used to help manage and treat diseases due to the phytochemicals, nutrients, and minerals present in them. Also, the safety indices of this plant part have been established, thus, information obtained from the study can serve as a reference standard for the plant monograph.
