The nanoencapsulation of essential oils for biodegradable films functionalization is a viable alternative for the production of active food packaging. In this study, the Cinnamodendron dinisii Schwanke essential oil was nanoencapsulated using zein as wall material, and applied in chitosan matrix to produce an active nanocomposite film packaging for food conservation. The chemical composition of the Cinnamodendron dinisii Schwanke essential oil showed a variety of unexplored bioactive compounds, and 1,8-cineole was the major compound. The oil nanoencapsulation produced stable and homogeneous nanoparticles with zeta potential close to 30 mV and polydispersity index lower than 0.2. The nanoparticles size showed a size variation between 70 and 110 nm. The chitosan films obtained functionalized with nanoparticles demonstrated antioxidant activity and antimicrobial activity. The active packaging containing zein nanoparticles was efficient in the conservation of ground beef, stabilizing the deterioration reactions and preserving the color.

control methods have proved to be inefficient, which justifies the search for new control measures. In this search for botanical insecticides for controlling , the following were evaluated: (i) the toxicity of essential oils (EOs) from , , and ; (ii) the effect of EOs on life table parameters against ; (iii) the chemical characterization of EOs; and (iv) the in silico interaction of the chemical constituents present in the three EOs with the molecular targets of . The EO from had the lowest LD (1.

The ticks Rhipicephalus microplus and Rhipicephalus sanguineus sensu lato (s.l) are of great importance to agriculture, veterinary medicine and public health. Due to a number of problems related to the use of synthetic acaricides, natural products emerge as promising substances for alternative tick control.

The objective of this study was to determine cytotoxic activity, hemolytic activity, and to evaluate the ability of the essential oil from Cinnamodendron dinisii to induce DNA fragmentation of human lymphocytes. The essential oil was obtained by hydrodistillation. Cytotoxic activity was determined by the MTT method.

Background: The current chemotherapy for cutaneous leishmaniosis (CL) has a series of drug limitations such as toxic side effects, long duration, high costs and drug resistance, which requires the development of new drugs or effective alternatives to the CL treatment. Essential oils (EOs) are complex mixtures of secondary metabolites from various plants. It has been shown that several EOs, or their constituents, have inhibitory activity against protozoa.
