In Vitro Antibacterial Activity

The chemical constituents of the essential oil obtained by hydrodistillation from the leaves of Calycolpus moritzianus (O. Berg) Burret, syn Psidium caudatum Mc Vaught, collected in November 2006 in Mérida State, Venezuela, were identified by GC-MS analysis. Thirty components (91.1% of the sample) were identified, of which the seven major ones were β-caryophyllene (21.9%), α-pinene (10.9%), viridiflorol (9.7%), β-selinene (6.1%), α-copaene (6.3%), α-selinene (5.3%) and γ-eudesmol (5.1%). The oil was found to have antibacterial activity against Staphylococcus aureus ATCC (6538) and Enterococcus faecalis ATCC (29212), with MIC values of 60 μg/mL and 180 μg/mL, respectively.

In Vitro Antibacterial Activity

The composition and antimicrobial activity of the essential oil from Verbesina negrensis Steyerm. leaves is reported. Analysis was performed by GC/MS. Major constituents were α-pinene (43.1%), α-humulene (13.8%), δ-cadinene (8.1%), limonene (4.6%) and bicyclogermacrene (4.2%). The essential oil showed in vitro activity against the Gram-positive bacteria Staphylococcus aureus ATCC 25923 and Enterococcus faecalis ATCC 29212 (MIC 500 and 350 μL/mL respectively).
