- Composition and biological activity of the essential oil peruvian lantana camaraPublication . Benites, Julio; Moiteiro, Cristina; Miguel, Graça; Rojo, Leonel; Lopez, José; Venâncio, Florência; Ramalho, Luís; Feio, Sónia; Dandlen, Susana; Casanova, Hugo; Torres, IvanThe composition of the essential oil from Lantana camara L. (Verbenaceae) obtained by hydrodistillation of the aerial parts was examined by GC, GC/MS, and 13C-NMR. The GC analysis showed that carvone is the most abundant monoterpene 75.9%, together with limonene 16.9%, accounting for 92.8% of the oil. The major components were also tested by 13C-NMR analysis of the essential oil. The L. camara oil was assayed against several microorganisms, showing moderate antibacterial activity against the human pathogen Staphylococcus aureus (MIC 200 μg/ml). High antioxidant activity evaluated by the Trolox equivalent antioxidant capacity assay (TEAC) was found (29.0 mmol Trolox/kg) and relative low anti-inflammatory activity due to its weak ability for inhibiting lipoxygenase (IC50 = 81.5 μg/ml).
