“…In another work, [13] found similar results using the essential oil of Cymbopogon citratus and its major component citral, obtaining a dose-dependent effect. Some studies have shown that essential oils have effects against all three forms of T. cruzi and this is probably due to essential oil properties such as low density and lipid solubility, which enable them to diffuse across cell membranes and break layers of polysaccharides, fatty acids and phospholipids, while also affecting some organelles and some cytoplasmic metabolic pathways [2,13,8].…”

In this study, the essential oils extracted from the peels of Citrus aurantifolia, Citrus limon and Citrus sinensis were chemically characterized and quantified. These essential oils and their standards limonene, citral and limonene + citral were evaluated (at concentrations ranging from 500 to 3.91 mL·mL −1 ) regarding their anti-trypanosome, antifungal and antibacterial activities. The chemical identification and quantification (by GC/FID and GC/MS) displayed the limonene as the major component of the three essential oils. It did not verified antitrypanosome activity for all treatments. Regarding antimicrobial activity, the results were satisfactory against Gram-negative bacteria (Staphylococcus aureus, Listeria. monocytogenes and Salmonella cholerasuis) and funghi (Aspergillus niger, A. flavus and A. carbonarius), except for the bacterium Pseudomonas aeruginosa, which showed no inhibition for any treatment used.

“…In recent decades, the antimicrobials of traditional plants have received great attention due to the resistance to commercial antibiotics developed by some microorganism [2,3]. An alternative to reduce the microorganism growth is using essential oils with antifungal and antibacterial properties [4][5][6][7].…”

“…A CBM determinada para estes óleos foram de 0,06% para óleo de C. cassia e 0,25% para os óleos de M. alternifolia e C. flexuosus. Santos et al (2012) pesquisando a ação antibacteriana do óleo essencial de folhas de Piper malacophyllum (pariparoba) sobre E. coli ATCC 25922 pelo método de microdiluição em caldo, encontraram uma CMB de 3700 µg/mL. Embora a atividade antibacteriana dos óleos essenciais utilizados neste trabalho seja bem conhecida, estes ainda não haviam sido avaliados contra a cepa ETEC.…”

RESUMO:Este trabalho teve por objetivo avaliar o efeito bactericida in vitro de dezesseis óleos essenciais sobre Escherichia coli enterotoxigênica (ETEC). Dentre os óleos essenciais estudados, três foram extraídos in situ por arraste a vapor e treze foram adquiridos comercialmente. Todos os óleos foram analisados por CG-EM e CG-DIC. A atividade bactericida foi avaliada pelo método de microdiluição utilizando-se caldo triptona de soja e microplacas de poliestireno de 96 poços, com posterior plaqueamento das culturas em ágar triptona de soja. Os óleos essenciais de Cinnamomum cassia e de Thymus vulgaris apresentaram concentração mínima bactericida (CMB) de 0,12% e 0,25%, respectivamente. Já os óleos comerciais de Syzygium aromaticum e Origanum vulgare apresentaram ambos CMB de 0,50% e os óleos extraídos in situ de Cymbopogon citratus e Origanum vulgare apresentaram ambos CMB de 1,00%. Os dezesseis óleos essenciais apresentaram composição química qualitativa e quantitativa distintas. As análises químicas dos óleos essenciais de Cinnamomum cassia e de Thymus vulgaris tiveram a presença majoritária de E-cinamaldeído (84,52%) e timol (50,89%). Conclui-se que os óleos de C. cassia e T. vulgaris foram os mais eficazes na inibição do crescimento in vitro dessa bactéria, a qual possui diferentes níveis de sensibilidade dependendo da composição química do óleo.

This study aimed to evaluate the bactericidal effect in vitro of sixteen essential oils on enterotoxigenic Escherichia coli (ETEC). Among the essential oils, three were extracted in situ by steam distillation and thirteen were purchased commercially. All oils were analyzed by GC-MS and GC-FID. The bactericidal activity was evaluated by the microdilution method using tryptone soy broth, and 96-well polystyrene microplates with subsequent plating of the cultures in tryptone soy agar. Cinnamomum cassia and Thymus vulgaris essential oils showed minimal bactericidal concentration (MBC) 0.12% and 0.25%, respectively. Both commercial oils of Syzygium aromaticum and Origanum vulgare showed MBC of 0.50% and the oils extracted in situ Origanum vulgare and Cymbopogon citratus showed both MBC of 1.00%. The sixteen essential oils pointed out distinct qualitative and quantitative chemical composition. Chemical analysis of Cinnamomum cassia and Thymus vulgaris oils had the predominant presence of E-cinnamaldehyde (84.52% ± 0.07%) and thymol (50.89% ± 0.31%). In conclusion, T. vulgaris and C. cassia oils were the most effective in inhibiting in vitro growth of this bacterium, which has different sensitivity levels depending on the chemical composition of the oil.

“…According to studies by Ref. [45], the essential oil of Piper malacophyllum collected in Florianopolis in the state of Santa Catarina showed signiicant antimicrobial activity, especially antifungal activity shown to be moderate against the Cryptococcus neoformans yeast and the Trichophyton mentagrophytes ilamentous fungus, both of clinical interest. This activity is atributed to the synergism of the chemical constituents present in the essential oil.…”

Piperaceae, a Latin name derived from Greek, which in turn originates from the Arabic word babary-black pepper, is considered one of the largest families of basal dicots, found in tropical and subtropical regions of both hemispheres. The species that belong to this family have a primarily pantropical distribution, predominantly herbaceous members, occurring in tropical Africa, tropical Asia, Central America and the Amazon region. The Piperaceae family includes ive genera: Piper, Peperomia, Manekia, Zippelia and Verhuellia.Brazil has about 500 species distributed in the Piper, Peperomia and Manekia genera. The Piper genus, the largest of the Piperaceae family, has about 4000 species. Within the Piper genus, about 260-450 species can be found in Brazil. Piper species have diverse biological activities and are used in pharmacopeia throughout the world. They are also used in folk medicine for treatment of many diseases in several countries including Brazil, China, India, Jamaica and Mexico. Pharmacological studies of Piper species point toward the vast potential of these plants to treat various diseases. Many of these species are biologically active and have shown antitumor, antimicrobial, antioxidant, insecticidal, antiinlammatory, antinociceptive, enzyme inhibitor, antiparasitic, antiplatelet, piscicide, allelopathic, antiophidic, anxiolytic, antidepressant, antidiabetic, hepatoprotective, amebicide and diuretic possibilities.
