Abstract:
Medicinal plants, either as standardized extracts or in their pure forms, offer countless propects for new drug leads and also possess a good range of nutritional benefits due to the presence of bioactive organic chemical compounds called phytochemicals that act as a defense against a variety of diseases. This study focus was to investigate the bioactive compounds, and identification of functional groups of three medicinal plants; Monodora myristica, Parkia biglobosa, and Azadirachta indica. The solvents used were methanol, water and ethanol respectively. Gas Chromatography- Mass Spectroscopy (GC-MS) assay was used for the analysis of bioactive compounds and Fourier-Transform Infrared Spectroscopy (FTIR) method was used for the identification of functional groups in the plant extracts. Results revealed several bioactive compounds at different peaks that were confirmed by their retention time, compound name, structure and percentage composition. FTIR analysis revealed different functional groups with distinct characteristic wave numbers, peak intensity, peak shape and bonds in the plant extracts. Among the identified phytocompounds of Monodora myristica, phenol, dodecanoic acid, hexadecane, n-hexadecanoic acid, 1-octadecene, and 1-eicosanol possess antioxidant property. Similarly, some of the identified phytocompounds of Parkia biglobosa; dodecanoic acid, hexadecanoic acid, 9-octadecene, naphthalene, 3-eicosene and n-hexadecanoic acid possess antioxidant property. Likewise, Hexadecane, hexadecenoic acid, 3-eicosene and n-hexadecanoic acid are phytocompounds of Azadirachta indica with antioxidant property. This study demonstrated these plants as a great source of naturally occurring bioactive compounds with therapeutic value, which supports their application in medicine to treat a variety of diseases.
