Now a days, phytochemical screening and GCMS analysis draw the attention of researchers, as it is the important tool to analyze secondary metabolites and bioactive compounds which are used to produce the herbal medicines, food colorants, flavors and fragrances. In this study bioactive compounds and phytochemical constituents of Jumbo muscadine grape pulp extract are analyzed. The extract has been characterized by UV and FTIR in which both the optical property and functional groups are identified. Absorption spectra of UV showed the highest peak at 270 nm which associates to the polyphenol and functional groups such as alcohol; alkene has been interpreted using FTIR spectrum. Presence of phytochemicals is confirmed by qualitative tests and quantified. Bioactive compounds are interpreted using gas chromatography–mass spectrometry analysis. This grape extract contains phenols, terpenoids, saponins and carbohydrates as major phytochemicals. Identified essential bioactive compounds of this extract include Glycerin, oleic acid, palmitic acid and 5-hydroxymethyl furfural.
