Abstract

This study aims to determine the chemical composition and evaluate the antibacterial activity of the essential oil of leaves dry lavender (Lavandula officinalis). The analysis of the essential oil indicates the presence of terpenes, tannins, saponins, flavonoids, alkaloid, coumarins, and the absence of anthocyanins. Furthermore, of the oil’s antimicrobial activity was evaluated using agar diffusion and broth microdilution methods. The antimicrobial test results showed that the oil had antimicrobial activity against all 8 microorganisms strains included in the study. Results suggest antimicrobial properties of the Lavandula officinalis essential oil, which may find its application in future research for the pharmaceutical industry.
