About the Cover

This study evaluates the antimicrobial properties, phytochemical composition, and thin-layer chromatographic (TLC) profiles of aqueous and ethanol leaf extracts of Nicotiana tabacum and Sesamum alatum. The preliminary phytochemical screening showed that alkaloids, tannins, saponins, flavonoids, glycosides, carbohydrates, proteins, terpenoids, and anthraquinones were present in both plants. Phytosterols were detected only in N. tabacum. TLC analysis of ethanol extracts revealed five phytocompounds for N. tabacum with Rf values of 0.06, 0.08, 0.12, 0.76, and 0.90, and six for S. alatum at 0.05, 0.10, 0.13, 0.21, 0.72, and 0.97. Antimicrobial analysis against some selected microorganisms showed that both extracts demonstrated concentration-dependent inhibition activities. In N. tabacum, the ethanolic extract showed the highest zone of inhibition (18 mm) against Staphylococcus aureus, while the aqueous extract showed more potency against Proteus vulgaris (15 mm). For S. alatum, the ethanol extract exhibited microbial inhibition against Klebsiella pneumoniae (23 mm).
