Phytochemical analysis and antioxidant activity assessment of methanolic extract from jasmine flowers

Abstract

This study offers a comprehensive analysis of the phytochemical composition and antioxidant properties of the methanol extracts from Jasmine flowers. Employing a combination of advanced techniques, including Gas-Chromatography Mass-Spectrometry (GC-MS), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and antioxidant activity assays, the research uncovered key insights into the bioactive potential of Jasmine. The GC-MS analysis identified nine distinct compounds, including major constituents, such as 2-Phenylthiolane (44.12%), Cyclohexene, 3-ethenyl- (25.88%), Acetaldehyde (12.70%), and N-Methylallylamine (10.31%) among others. The FTIR spectra revealed significant functional groups, including O-H and C-C stretches, suggesting the presence of phenolic compounds. The SEM imaging highlighted the morphological changes in the Jasmine flower powder, showing expanded oil glands post-pre-treatment, which enhanced the oil extraction process. The methanol extract exhibited a strong antioxidant activity, as evidenced by the DPPH radical scavenging assay. These findings position Jasmine flowers as a promising natural source of phytochemicals, particularly antioxidants, with potential for further pharmacological and industrial applications. Future studies could focus on isolating and evaluating additional bioactive compounds for their therapeutic potential
