The study aimed to analyze: • Morphological characteristics. • Preliminary chemical composition of the stem. • In vitro antibacterial activity of the 70% ethanol stem extract. Methods included: • Morphological and histological analysis. • Preliminary phytochemical screening using the Ciuley method. • In vitro antibacterial activity assessment via agar well diffusion against Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli. Key findings: • The stem contained carotenoids, coumarins, triterpenoids, saponins, flavonoids, and reducing sugars. • The 70% ethanol extract showed in vitro antibacterial activity against all tested bacteria at 200 mg/mL, with the highest activity against Staphylococcus aureus. In conclusion, the study provided data for identifying V. amygdalina and suggested that the stem extract has antibacterial potential. Further research on specific compounds and other biological activities is recommended.
