“…In general, the essential oil showed better activity than the methanol extract. This observation agrees with previous reports by Vukovic et al (2007) and Sokmen et al (2004) that methanol extracts showed less activity than essential oil [10], [12].…”

“…Totally, the Gram-positive bacteria are more susceptible than Gram-negative bacteria due to the differences in their cell wall structure. Gram-negative organisms are considered to be more resistant due to their outer membrane acting as a barrier to many environmental substances, including antibiotics [8]- [10]. However, the results from this study reveals that the essential oils of Achillea wilhelmsii leaves rich in monoterpenes, including: camphor , 1, 8 -cineole, borneol and myrtenol [11].…”

Abstract-Achillea wilhelmsii is belong to Asteraceae family. This plant is from medicinal plants in Iran customary medicine.The aim of this study was to appraise of effects of the leaves essential oil and methanol extract of the Achillea wilhelmsii on the growth of the bacteries. In this study after collecting and provision plant, leaves essential oil were obtained by hydrodistillation and leaves methanol extract were obtained using a Soxhlet apparatus. The effects of methanol extract antimicrobial were assessed using Agar Well Diffusion method and also using Dilution Test method. The effects of essential oil antimicrobial were determined by using Agar Dilution Assay. Dates were analyzed using Chi-square and AVONA test in the p <0/001.Leaves methanol extract had more effect against Bacillus cereus and Staphylococcus aureus bacteries and showed weak effect against Escherchia coli and was not abserved any growth inhibition effect against Pseudomonas aeroginosa,also leaves essential oil had inhibition effect against Bacillus cereus, Staphilococcus aureus and Escherchia coli and did not have any inhibition effect against Pseudomonas aeroginosa.Leaves methanol extract and essential oil of Achillea wilhemsii have antibacterial effects,therefore we will be able perform researches with extraction of this plant effective compound for the treatment of infectious diseases.

“…De forma geral, o OE exibiu maior atividade do que o EE (Tabela 3), sugerindo que haja maior concentração de compostos químicos ativos contra o S. aureus no OE do que no EE de A. zerumbet. Resultados similares foram observados, cuja ação de OE se sobrepõe aos de extratos obtidos com a mesma espécie medicinal, diante de S. aureus (Vukovic et al, 2007;Gonçalves et al, 2008).…”

ABSTRACT:The present work describes the antibacterial activity of the essential oil and the ethanol extract from leaves of Alpinia zerumbet (colônia) on Staphylococcus aureus strains isolated from cows with subclinical mastitis and standard strains ATCC 29213 and ATCC 25923, using the agar diffusion method. Ten treatments containing different concentrations of essential oil and ethanol extract (100.0; 50.0; 25.0; 12.5 and 6.3 mg.mL ) and the control group (50% ethyl alcohol and 1% Tween solutions) were used for antimicrobial testing. The major constituents of the essential oil were p-cimeno (32.72%), 1.8-cineol (24.05%) and 4-terpineol (20.23%), which were determined by gas chromatographymass spectrometry and gas chromatography -flame ionization detector (CG-MS/FID). Ellagic acid and three flavonoids (rutin, quercetin and campferol) were detected in the ethanol extract by means of high performance liquid chromatography-photodiode array detector (HPLC-PDA). All strains showed sensitivity to the treatments with essential oil and the ethanol extract. The best response was obtained with A. zerumbet essential oil at a 100 mg.mL ) e o grupo controle (álcool etílico a 50% e Tween a 1%). Os constituintes majoritários do óleo essencial foram p-cimeno (32,72%), 1,8-cineol (24,05%) e 4-terpineol (20,23%), sendo esses determinados por cromatografia a gás acoplada a espectrometria de massas e cromatografia a gás com detector de ionização de chama (CG-EM/DIC). No extrato etanólico foi detectado o ácido elágico e três flavonoides: rutina, quercetina e campferol, por meio de cromatografia a líquido de alta eficiência acoplada a detector de arranjo de diodo (CLAE-DAD). Todas as cepas apresentaram sensibilidade aos tratamentos com óleo essencial e extrato etanólico. A melhor resposta foi obtida com o óleo essencial de A. zerumbet que, na concentração de 100 mg.mL -1 proporcionou inibição total do crescimento bacteriano. Esses resultados sugerem o potencial antibacteriano do óleo essencial e do extrato etanólico de A. zerumbet no controle da mastite bovina.

Comparative study of genotoxicity and antimutagenicity of methanolic extracts from Teucrium chamaedrys and Teucrium montanum in human lymphocytes using micronucleus assay

et al. 2013

Since Teucrium chamaedrys and Teucrium montanum are the most popular plants used in the treatment of many diseases, we evaluated genotoxic potential of their methanolic extracts on cultured human peripheral blood lymphocytes (PBLs) using cytokinesis-block micronucleus (MN) assay. Cultures were treated with four concentrations of both plants (125, 250, 500 and 1,000 lg/ml), both separately and in combination with mitomycin C (MMC). The results revealed that extract of T. chamaedrys administered at the tested concentrations did not significantly affect the mean MN frequency in comparison to untreated cells. Methanolic extract of T. montanum increased the mean MN frequency in PBL at the tested concentrations, but significantly only at the concentration of 1,000 lg/ml. In all tested concentrations, the extract of T. chamaedrys significantly reduced the MMC-induced MN frequency, in a dose dependent manner (r = -0.687, p \ 0.01). The extract of T. montanum decreased the MMC-induced MN frequency at the tested concentrations, but statistically only at 125 lg/ ml. Both extracts administered alone did not significantly affect the nuclear division index (NDI) at the tested concentrations. In the combined treatments with MMC, the extract obtained from T. chamaedrys in the concentrations of 500 and 1,000 lg/ml significantly decreased NDI values in comparison to MMC-treated cells alone, while the extract of T. montanum significantly decreased NDI at all tested concentrations. Both extracts nonsignificantly decreased NDI at all tested concentrations in comparison to untreated cells. Our results suggest the important function of T. chamaedrys extract in cancer therapy, this methanolic extract may prevent genotoxic effects of chemotherapy in PBLs.
