This study will concentrate on determining the phytochemical properties of Coleus blumei (Mayana) leaf ethanolic extract and Musa acuminata (Banana) peel ethanolic extract. It will also focus on comparing the presence of antioxidant properties on both plant materials. This research comprises the usage of ethanol for the extraction of the leaves of Coleus blumei (Mayana) and the peel of Musa acuminata (Lakatan) to obtain the wanted samples for the experiment. The ethanolic extract of the plant materials will be subjected to different phytochemical screenings to detect if it contains chemical constituents that are medicinally active. The phytochemical screening will be limited to detecting the presence of alkaloids, flavonoids, steroids, saponins, phenols, tannins, and glycosides only. Following that, they will perform 2,2-diphenyl-1- picrylhydrazyl (DPPH) assay to detect the antioxidant activities of both materials and to see if there is a significant difference between the two plant samples. The collection of the materials is limited only to the vicinity of Cavite and this research is limited within the campus of De La Salle Medical and Health Sciences Institute (DLSMHSI). The experimentation phase is bound within four months, starting from January 2020 up to May 2020. The research will involve also the Center for Basic Biomedical Research, Angelo King Medical Research Center for extraction of Coleus Blumei (Mayana) leaves and Musa acuminata (Lakatan banana) peels, phytochemical screening, and DPPH assay.
