Abstract: Lippia sidoides Cham. has widespread use in folk medicine because its essential oil (EO) presents great antibacterial properties. In Brazil, this plant has been introduced in governmental programs for herbal medicine, due to its recognized therapeutic activities. This promoted greater interest in the search for new molecules with antimicrobial activity in this EO which have been described by several authors. Thus, this work aimed to present a study of the scientific production of antibacterial activity of the chemical compounds from L. sidoides essential oil (LSEO). The inclusion criteria were articles which assessed the chemical components and antibacterial activity through the inhibition diameter, Minimum Inhibitory Concentration (MIC), and Minimal Bactericidal Concentration (MBC), published between 2000 and 2020. Of the 996 studies identified, 55 met the inclusion criteria. In descending order, the most frequently detected chemical components found in LSEO were: thymol, p-cymene, and caryophillene. Regarding to the origin, the results showed that the extraction of EO were carried out mainly in the Northeast (55.5%) and Southeast (19%) regions of Brazil; and the part of the plant most used for the production were the leaves. In addition, the essential oil showed strong antibacterial activity against most of the bacteria tested. -- Resumo: Lippia sidoides Cham. é amplamente utilizada na medicina popular devido às propriedades antibacterianas atribuídas ao seu óleo essencial (OE).

Assim, este trabalho objetivou apresentar um estudo da produção científica da atividade antibacteriana dos compostos químicos do OE da L. sidoide.

De um total de 996 estudos identificados, 55 preencheram os critérios de inclusão. Em ordem decrescente, os componentes químicos mais comumente encontrados no OE da L. sidoide foram: timol, p-cimeno e cariofileno. Com relação à origem, os resultados mostraram que a extração do OE foi realizada principalmente nas regiões Nordeste (55,5%) e Sudeste (19%) do Brasil; e a parte da planta mais utilizada para a produção foram as folhas.

The objective of this work was to assess the effects of pH and ionic strength upon zinc adsorption, in three highly weathered variable charge soils. Adsorption isotherms were elaborated from batch adsorption experiments, with increasing Zn concentrations (0?80 mg L-1), and adsorption envelopes were constructed through soil samples reactions with 0.01, 0.1 and 1 mol L-1 Ca(NO3)2 solutions containing 5 mg L-1 of Zn, with an increasing pH value from 3 to 8. Driving force of reaction was quantified by Gibbs free energy and separation factor. Isotherms were C-, H- and L-type and experimental results were fitted to nonlinear Langmuir model. Maximum adsorption ranged from 59?810 mg kg-1, and Zn affinity was greater in subsoil (0.13?0.81 L kg-1) than in the topsoil samples (0.01?0.34 L kg-1). Zinc adsorption was favorable and spontaneous, and showed sharply increase (20?90%) in the 4?6 pH range. No effect of ionic strength was observed at pH values below 5, because specific adsorption mechanisms predominated in the 3?5 pH range. Above pH 5, and in subsoil samples, Zn was adsorbed by electrostatic mechanisms, since ionic strength effect was observed. Despite depth and ionic strength effects, Zn adsorption depends mainly on the pH. |
