The essential oil obtained from the leaves of Lantana camara var. moritziana (Otto & Dietr.) López-Palacios collected at Rubio, Táchira State, Venezuela, was obtained by hydrodistillation in a Clevenger trap (0.1% yield). The oil was analyzed by gas chromatography-mass spectrometry (GC/MS) on HP GC-MS System, model 5973, identifying 33 compounds (97.1%) of which the major components were germacrene D (31.0%), followed by β-caryophyllene (14.8%), α-phellandrene (6.7%), limonene (5.7%) and 1,8-cineole (5.2%). Evaluation of the antibacterial activity by agar diffusion method with discs against international reference bacteria ( Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae, Salmonella Typhi, Pseudomonas aeruginosa) showed growing inhibition of E. faecalis and S. aureus at MIC of 350 mg/mL and 400 mg/mL, respectively.

In the present study, chemical composition and antibacterial properties of essential oil obtained from the aerial parts of the Melicope pteleifolia (Champ. ex Benth.) T.G Hartley in Dalat were evaluated. Essential oil was isolated through hydro-distillation. Twenty-nine constituents comprising 100% of the essential oil were characterized by gas chromatography/mass spectrometry (GC-MS) techniques. The major compounds in the essential oil were (+)-Sabinene (34.73%), Cis-α-bergamotene (13.15%), Z-α-trans-bergamotol (5.28%), β-mycrene (4.98%), and 1,3,6-octatriene, 3,7-dimethyl-(4.71%). Antibacterial activities of Melicope pteleifolia essential oil were investigated against Gram-positive and-negative bacteria. Results showed significant activities against Streptococcus pyogenes and Escherichia coli using an agar well diffusion method. The application of this essential oil in preventing and eliminating bacteria could be useful in fields as medicine and cosmetics.

Leaf Oil

Essential oils obtained by hydrodistillation of leaves of two Nigerian species were analyzed for their constituents by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The leaf oil of Ficus benjamina L. (Moraceae), collected during the day, contained high contents of α-pinene (13.9%), abietadiene (9.7%), cis-α-bisabolene (8.2%) and germacrene-D-4-ol (8.4%), while the night sample was dominated by germacrene-D-4-ol (31.5%), 1,10-di- epi-cubenol (8.8%) and hexahydrofarnesylacetone (8.3%). This could be a possible indication of differences in emissions of volatiles by F. benjamina during the day and night. The main compounds of Irvingia barteri Hook. f. (Irvingiaceae) were β-caryophyllene (17.0%), (E)-α-ionone (10.0%), geranial (7.6%), (E)-β-ionone (6.6%) and β-gurjunene (5.1%).

The purpose of this study was to evaluate the essential oil composition as well as antibacterial activities of essential oil of Lantana camara L flowers against four bacterial strains. Essential oil of Lantana camara L flowers was obtained by hydrodistillation method using Sthal and analyzed by GC-MS. The antibacterial activities of essential oil were tested by using disk diffusion method against four bacterial strains. Results showed  72 compounds for Lantana flowers essential oil, of which caryophyllene   (10,87%),   davanone   (9.84%),   a-humulene   (7.59%),   a-curcumene (3.35%), germacrene D (3.09%), calarene (2.42%), a-muurolene (2.27%), p-cymene (1.79%), 1,8 cineole (1.59%) , δ-cadinene (1.59%), a-copaene (1.12%), nerolidol B (1%) and ß-ocimene (0.54%) were detected as major components. Antibacterial activity assay of Lantana camara L flowers essential oil was examined against four bacterial strains including Gram (+and-) by using disk diffusion agar method. All the tested Gram (+and-) bacterial strains displayed slight to moderate antibacterial activity (7 – 10 mm) against all concentrations of essential oil. The essential oil of Lantana camara L flowers showed remarkable antibacterial activity with inhibition in concentrations of 10% and 20% against the phatogen bacterias Basillus subtilis (9.6 mm; 10.8 mm), Propionibacterium acnes ( 7.6 mm; 8.7 mm), Eschechia coli ( 8.4 mm ; 9.6 mm) and Pseudomonas aeruginosa ( 8.3 mm ; 9.3 mm) showed from zone of inhibition that was formed, zone of inhibition in concentration 20% was bigger than concentration 10%.
