Chemical constituents of the essential oil from the leaves of Minthostachys mollis (Kunth) Griseb Vaught var. mollis collected in January 2008 at Tuñame, Trujillo State, Venezuela, were separated and identified by GCMS analysis. The essential oil was obtained by hydrodistillation and thirteen components (98.5% of the sample) were identified by comparison with the Wiley GCMS library data base. The two major components were pulegone (55.2%) and trans-menthone (31.5%). The essential oil showed a significant inhibitory effect against Gram-positive and Gram-negative bacteria, especially Bacillus subtilis and Salmonella typhi (4 μg/mL).

The essential oil from the air dried powder of wild Acorus calamus L. rhizomes was isolated using Clevenger-type hydrodistillation apparatus and its chemical constituents were analyzed by gas chromatography-mass spectrometric (GC-MS) analysis. A total numbers of fourteen chemical constituents were identified and quantified occupying 100 % of total oil composition. The major chemical constituents are reported to be β-asarone (68.96 %), 4-hydroxy-4-methyl-2-pentanone (8.73 %) shyobunone (8.65 %), p-methoxyphenyl butanone (4.16 %) and the minor chemical constituents are δ-cadinene (0.84 %), isoelemicine (2.68 %), muurolene (1.92 %) and cis-ocimene (1.44 %). The antibacterial activity of the essential oil isolated from the wild Acorus calamus L. rhizomes was carried out using paper disc method against one Gram positive bacteria of Staphylococcus aureus and three Gram negative bacteria of Escherichia coli, Klebsiella pneumoniae and Proteus vulgaris. The isolated essential oil from the dry powder of Acorus calamus L. rhizome showed a good potentiality of the antibacterial effect against tested bacteria.

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.

The chemical constituents of Psidium guajava essential oil was analyzed by using Gas Chromatography-Mass Spectrometry. The essential oil was obtained from dried leaves by hydrodistillation method using a Clevenger apparatus. From the initial screening, 20 components were detected with different amounts traced. The most abundant constituents observed in the oil were Limonene (23.39%), Caryophyllene (18.19%), Cyclooctasiloxane (14.46%), and Pinene (13.50%). The essential oil showed significant antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Enterococcus faecalis and Bacillus cereus with inhibition range of 6-25 mm. The profile of chemical constituents present in the oil able to serve as preliminary screening of the bioactive components posses in a natural plants for investigating antibacterial properties in regenerative medicine.

The antibacterial activity of the essential oil from leaves of Juniperus phoenicea (Cupressaceae) and its chemical constituents were investigated in this study. The essential oil was obtained by hydrodistillation and analyzed by gas chromatography equipped with a flame ionisation detector (GC-FID), and gas chromatography coupled to a mass spectrometer (GC-MS). Sixty-three volatile compounds were identified representing 52 to 92% of the total oil compositions. The main monoterpenes were α-pinene (26.7-78.7%) and δ-3carene (7.6-15.4%). The antibacterial activity of J. phoenicea essential oil, when tested against both Gram-positive and Gram-negative bacteria, showed high activity against all bacteria tested, except Pseudomonas.

To evaluate the antibacterial activity and chemical constituents of the essential oil from the artemisia argyi grown in Qichun (China). METHODS: Steam distillation method was used to extract volatile oil from Artemisia argyi. The antibacterial effect of the volatile oil was investigated by the plate coating method and the double gradient liquid dilution method. Gas chromatography-mass spectrometry(GC-MS) was applied for the identification of chemical constituents in volatile oil from Artemisia argyi and the relative percentage of each component was calculated by area normalization. RESULTS: The essential oil from artemisia argyi grown in Qichun (China) has significant antibacterial activity against staphylococcus aureus, pseudomonas aeruginosa, salmonella, candida albicans, aspergillus niger and aspergillus flavus. And fifty chemical components were detected in the essential oil, and twenty compounds were identified, accounting for 95.95% of total essential oil. And the artemisol in artemisia argyi grown in Qichun (China) was found to be the highest compared with the same species from other producing areas. CONCLUSION: The essential oil from artemisia argyi grown in Qichun (China) was a potent antibacterial plant extract with potential applications as an antibacterial drugs or food preservative.
