Pharmacognostic Standardization, Phytochemical Profiling, and Pharmacological Evaluation of Jasminum officinale L.: A Comprehensive Study

Jasminum officinale L. (Oleaceae), commonly known as common jasmine, has been traditionally employed in multiple medicinal systems. This study comprehensively evaluates its pharmacognostic characteristics, phytochemical constituents, and pharmacological properties, particularly its antioxidant and antibacterial activities. Methanolic extraction of the plant yielded 2.79% w/w extract. Pharmacognostic parameters such as ash values and moisture content confirmed the identity and quality of the crude drug. Phytochemical screening revealed the presence of multiple classes of secondary metabolites, with quantitative estimations showing notable levels of flavonoids, saponins, and alkaloids. LC-MS analysis identified major bioactive compounds including quercetin-3-O-glucoside, rutin, and luteolin derivatives. Antioxidant assays (DPPH and H2O2 scavenging) and antibacterial assays against five clinically significant bacterial strains established the moderate to strong bioactivity of the extract. The results support the traditional uses of J. officinale and highlight its potential as a source of novel bioactive compounds.
