RESUMO

<p><b>OBJECTIVE</b>To evaluate the antibacterial activity of the essential oil of Myrtus communis (M. communis) L. against Erysipelothrix rhusiopathiae (E. rhusiopathiae) in vitro.</p><p><b>METHODS</b>Wild populations of M. communis collected from Khuzestan and Lorestan provinces, Southwest Iran, were examined for antibacterial activity and chemical variability in leaves. The in vitro antibacterial activity against E. rhusiopathiae was performed by agar disc diffusion and micro-dilution assays.</p><p><b>RESULTS</b>The essential oils of M. communis have strong antibacterial against E. rhusiopathiae in both assays. The results showed that the major components of the oil were α-pinene (22.3%-55.2%), 1,8-cineole (8.7%-43.8%) and linalool (6.4%-14.5%). The inhibition zones and MIC values for bacteria which were sensitive to the essential oils of M. communis were in the range of 14.7-27.0 mm and 0.031-0.25 mg/mL, respectively.</p><p><b>CONCLUSIONS</b>This study demonstrates that products with valuable antibacterial activity can be produced from leaves of M. communis against E. rhusiopathiae.</p>

RESUMO

<p><b>OBJECTIVE</b>To examine the chemical variability in inflorescences of wild populations of Stachys lavandulifolia Vahl (S. lavandulifolia) collected throughout two provinces (Isfahan and Chaharmahal va Bakhtiary), Southwest Iran.</p><p><b>METHODS</b>The essential oils of S. lavandulifolia Vahl from seven locations were obtained by hydro-distillation and analysed by gas chromatography and gas chromatography-mass spectrometry.</p><p><b>RESULTS</b>The results revealed that distinct differences in the content of compounds depending on region of sample collection. The main constituents of the essential oils were α-thujone (0.3%-32.3%), α-pinene (trace to 37.3%), myrcene (0.5%-15.9%), β-phellandrene (1.1%-37.9%), germacrene D (0.4%-11.3%), Δ-cadinene (trace to 11.6%) and 1, 4-methano-1 H-indene (trace to 10.1%).</p><p><b>CONCLUSIONS</b>The results of the present study indicated that essential oil components of S. lavandulifolia Vahl can be varied with genetic (ecotype), environmental conditions and geographic origin. In general, the essential oils of various populations of S. lavandulifolia Vahl were rich in monoterpenoids and sesquiterpenoids.</p>
