**4. Conclusion**

The essential oils of the leaves and roots of *A. flagellaris* and their chemical makeup, antioxidant and antibacterial capabilities. The oil samples from the leaves and roots, respectively, contained 28 and 19, mostly oxygenated monoterpenes, oxygenated sesquiterpenes, hydrocarbon sesquiterpenes, oxygenated diterpenes and thymol and its derivatives. The essential oil shown significant antioxidant activity when compared to common medicines. The essential oil at a concentration between 500 and 125 μg/mL exhibited moderate activity against all the tested microorganisms, according to the inhibition zones (10–18 mm) obtained from the antimicrobial assay, in comparison to the standard drugs (gentamicin; 10 μg/mL and tioconazole; 0.7 mg/ mL), which gave 26-40 mm inhibition zones. The chemical elements and biological activity of the *A. flagellaris* leaves and roots essential oil support the ethnomedicinal usage of this plant for treating syphilis, gonorrhea and other sexually transmitted disorders.
