The present study was carried out to determine, for the first time, the chemical composition and antibacterial activity of essential oils derived from the aerial parts of three aromatic plants Thymus algeriensis Boiss & Reut, Rosmarinus officinalis L., and Salvia officinalis L. growing under semiarid conditions. The essential oils were chemically analyzed and identified by gas chromatography (GC) and GC/ mass spectrometry (GC/MS) and their antimicrobial activity was individually evaluated against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa using both agar disk diffusion and agar dilution methods. The major constituents of Thymus algeriensis essential oil were identified as camphor (13.62%), 1,8-cineol (6.00%), borneol (5.74%), viridiflorol (4.00%), and linalool (3.93%). For Rosmarinus officinalis essential oil, 48 compounds were characterized, of which the main constituents were camphor (17.09%), Z-β-ocimene (10.88%), isoborneol (9.68%), α-bisabolol (7.89%), and borneol (5.11%). While, Salvia officinalis essential oil was characterized by β-thujone (16.44%), followed by viridiflorol (10.93%), camphor (8.99%), 1,8-cineol (8.11%), trans-caryophyllene (5.85%), and α-humulene (4.69%) as the major components. Notably, results from antibacterial screening indicated that Thymus algeriensis and Salvia officinalis essential oils exhibited a strong inhibitory effect against both Escherichia coli and Staphylococcus aureus compared to Rosmarinus officinalis essential oil. Further, less activity was recorded against Pseudomonas aeruginosa for the three tested essential oils.

cinnamon dating from 1000 AD when it was firstly recorded in English due to its important as aroma and as herbs. The aim of this study was to investigate phytochemicals constitutes, chemical composition and antimicrobial activity of the essential oil of commercial samples of Cinnamon verum bark. The essential oil was extracted by hydrodistillation, while the crude extracts were prepared by three different solvents methanol (70%), acetone and aqueous. Phytochemical screening of crude extracts was performed using standard methods. The essential oil was subjected to GC-MS analysis and tested against Staphylococcus aureus, Salmonella typhimurium, Pseudomonas aeruginosa, Eschericchia coli and Candida albicans. The obtained results indicated the presence of alkaloids, flavonoids, coumarin, tannins, terpenoids, saponin, glycoside, anthrocyanin and phenolic compounds in the methanolic, aqoueous and acetone extracts of C. verum bark; while the major components of the extracted essential oil of C. verum bark were cinnamaldehyde (85.50%), stigmasterol (3.69%), Cadinene (1.37%), (E)-cinnamaldehyde (1.35%), alpha-amorphene (1.33%), hydrocinnamaldehyde (1.28%), alpha-cubebene (1.25) and ergosterol (1.09%) respectively. The antimicrobial activity result indicated the high activity of the extracted essential oil against all tested microorganisms at high concentration; except in S. typhimurium and C. albicans at concentrations of 25% and 12.5% no activity was noticed. Based in our obtained results the essential oil of C. verum bark had high potential as antimicrobial agent, therefore, recommended for more advanced studies to be conducted on this abundant plant as natural source of antibiotics.

We wish to report the study of the antimicrobial activity of plants collected in the vicinity of a geothermal area in Perak, Malaysia. This is the first report of these species in the vicinity of thextis geothermal area. The plants are Cleome icosandra, locally known as Maman Pasir of the family Cleomaceae, and Stachytarpheta species of the family Lamiaceae. Both are subshrubs and are believed to have specific biological activities as a result of living in such extreme areas. Methanol extracts of both plants revealed no antimicrobial activity against Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa.
