The chemical composition of the essential oils of S. hierosolymitana Boiss. and S. multicaulis Vahl. var. simplicifolia Boiss. collected in Lebanon was studied by means of GC and GC-MS analysis. In all 115 compounds were identified: 82 for S hierosolymitana and 72 for S. multicaulis var. simplicifolia. The presence of carbonylic compounds (17%) characterizes the oil from S. hierosolymitana,whil...

bunium persicum (boiss.) is an economically important medicinal plant growing wild in arid regions in iran. the essential oil of b. persicum (eobp) was extracted using hydrodistillation. a total of eighteen compounds, representing 96.14 % of the oil was identified by gas chromatography/mass spectrometry (gc/ms).the main compounds were cuminaldehyde (23.04 %), gamma-terpinene (14.48 %), trans-3-...

Background: Iran is a land of great heritage of ancient medical scholars. Herbal medicines, as a basement of treatment of diseases have been clearly described in the medical texts of these scholars including Rhazes, Avicenna, and others. Numerous plants are introduced in these texts to treat those diseases likely to be infective ones. Few attempts have been made to evaluate ethnopharmacological...

Biological production of silver nanoparticles, due to its high antimicrobial properties and environmental compatibility, can be used as an alternative to antibiotics. The aim of this study was to optimize the green synthesis of silver nanoparticles using fruit extract of Bunium persicum Boiss and investigate the antimicrobial effect of nanoparticles against Escherichia coli and Staphylococcus a...

The ethanol extract of Teucrium manghuaense grown in Hainan province (China) was analysed by GC and GC/MS. Of the constituents 84-96% were identified on the basis of their GC retention times and their mass spectra in regard to authentic compounds. The results revealed that it contained 9-methyl-9-azabicyclo[4.2.1]nonane (7.43%), 2-methylpyrrolidine (19.42%), 3,7,11,15-tetramethyl-2-hexadecen-1-...

The chemical composition and antioxidant activity of different extracts (diethyl ether, ethyl acetate and n-butanol) obtained from Teucrium species (T. chamaedrys, T. montanum, T. polium) were investigated in this work. Phytochemical screening of the plant extracts proved the presence of flavonoids luteolin, apigenin and/or diosmetin. The chemical composition of extracts was evaluated by HPLC a...

This study was designed to examine the chemical composition of essential oil and the in vitro antimicrobial activities of essential oil and methanol extract of Teucrium montanum. The inhibitory effects of essential oil and methanol extracts of T. montanum were tested against 13 bacterial and three fungal species by using disc-diffusion method. GC/MS analyses revealed that essential oil contains...
