Phytochemical screening, Fourier transform infrared spectroscopy, and gas chromatography–mass spectrometry analysis of star jasmine (Jasminum multiflorum) flower petals

The Jasminum multiflorum which is a flowering plant belongs to Oleaceae family is commonly grown in tropical and subtropical areas for both its decorative qualities and the production of essential oils. In addition to its cultural and esthetic value, the species has prospective medicinal uses. Using sophisticated analytical methods and solvent-based extraction, this study examines the phytochemical makeup of J. multiflorum . Five distinct solvents were used in the phytochemical screening process to find important bioactive chemicals. Flavonoids, alkaloids, phenols, and other secondary metabolites were found by the analysis. A chemically varied profile was indicated by the 27 functional groups that were discovered by Fourier transform infrared spectroscopy, which included halo compounds, alkenes, amines, alcohols, anhydrides, esters, ethers, sulfonamides, alkanes, phenols, hydrocarbons, and nitro compounds. Multiple bioactive ingredients were validated by further analysis of methanolic and other solvent extracts using gas chromatography–mass spectrometry. When spectral data and the NIST Mass Spectral Library were compared, molecules with known pharmacological characteristics – such as antibacterial, anti-inflammatory, and antioxidant – were discovered. These results highlight J. multiflorum’s therapeutic potential and encourage further research into new uses in environmental health, natural product chemistry, and medicine.
