Abstract
Background: The present experiment was designed to determine the bioactive constituents from extracts of leaves of Phragmenthera capitata and Latana camara. The medicinal value of a plant species is dependent upon its various phytochemical constituents. Methodology:The chemical compositions of the ethanolic extract of the leaves of P. capitata and L. camara were investigated using theGas Chromatography-Mass spectrometry model GCMS-QP2010 PLUS SHIMADZU. The column used was aPerkin Elmer Elite – 5 capillary columns measuring 30m × 0.25mm with a film thickness of 0.25mm composed of 95% Dimethylpolysiloxane. The carrier gas used was Helium at a flow rate of 0.5ml / min. Results:Fifteen (15) bioactive phytochemical compounds were identified for P. capitata and twenty (20) bioactive phytochemical compounds were identified for L. camara. The prevailing compounds in P. capitata were, 3-H-pyrazol-3-1, Decanoic acid, n-Hexadecanoic acid, Pentanoic acid, Methyloctanoic acid, 4-octanoicacid, 15 -tetraosenoic acid, oleic acid, Octadecanoic acid, Pentafluoropropronic acid, (E)-13-docosenoic acid, Vitamin E, Lupeol and Chilosyphone. Also, in L. camara the following compounds were identified, 3-n-hexythiolane, Docosanoic acid, 1- nonanol, 1-hexacosanol, Divalonic acid, Decanoic acid, Octanoic acid, Eicosanoic acid, Hexadecanoic acid, Nonadecanoic acid, 9-12 octadecanoic acid, 11 -octadecadienoic acid, Pentadecanoic acid, Oleic acid, Methyl -Beta-D-arabinopyranoside, Acetic acid, Pentanoic acid, Heneicosanoic acid, methyl ester and 2H-pyran,2-(7-heptadecynloxytetrahydro. Conclusion: Based on the results of findings, it could be concluded that extract from P. capitata and L. camara may have antioxidant, antimicrobial, anti-cancer, anti-diabetic, anti-fungal and anti-convulsant activities due to the presence of secondary metabolites in the ethanolic extract
