Essential oils arouse the interest of research for insect control. Schinus terebinthifolius is described in the literature for being bioactive against Aedes aegypti larvae. However, studies are scarce to fully assess the larvicidal potential of this species. This study aimed to evaluate the chemical composition, bioactivity, time of death and bioavailability of the essential oil from different parts of S. terebinthifolius obtained from the Brazilian cerrado on Ae. aegypti larvae. For this, plants grown in the city of Goiânia-GO were used and the elucidation of the chemical composition of essential oils was carried out by means of gas chromatography coupled with mass spectrometry. Ae. aegypti larvae were used in the bioassays to assess larvicidal activity, determine the time of death and bioavailability of the essential oil in solution. In addition, the interference of essential oil in the activity of the enzyme acetylcholinesterase was also investigated. Based on the results obtained, it was observed that the most promising essential oil for the development of larvicidal formulations is that of fruits, based on having higher yield, greater bioactivity, time of death similar to synthetic insecticides. An inhibitory interaction of acetylcholinesterase was also observed. However, the essential oil had low bioavailability, so it is necessary to develop formulations to increase its bioactivity period.

Coriandrum sativum L. belongs to the Apiaceae family, which is cultivated in Dong Nai province, in this paper its seed oil of was studied. The essential oil was extracted by hydrodistillation. We used two methods for activating of hydrodistillation: conventional heating and microwave irradiating. Its physical and chemical indexes were measured. The chemical composition of this oil was identified by GC/MS and quantified by GC/FID. Linalool (75.51-77.21 %), and geranyl acetate (15.64-12.79 %) were the main constituents of the oil which were obtained in 0,32-0.39 % yield. The biological activity of this oil was reported.

Foeniculum Vulgare

Medicinal plants are considered modern resources for producing agents that could act as alternatives to antibiotics in demeanor of antibiotic-resistant bacteria. The aim of the study was to evaluate the chemical composition and antibacterial activities of essential oil of Foeniculum vulgare (FV) against Pseudomonas aeruginosa and Bacillus subtilis. Gas chromatography mass spectrometry was done to specify chemical composion. As a screen test to detect antibacterial properties of the essential oil, agar disk and agar well diffusion methods were employed. Macrobroth tube test was performed to determinate MIC. The results indicated that the most substance found in FV essential oil was Trans-anethole (47.41 %), also the essential oil of FV with 0.007 g/ml concentration has prevented P. aeruginosa and with 0.002 g/ml concentration has prevented B. subtilis from the growth. Thus, the research represents the antibacterial effects of the medical herb on test P. aeruginosa and B. subtilis. We believe that the article provide support to the antibacterial properties of the essential oil. The results indicate the fact that the essential oil from the plant can be useful as medicinal or preservatives composition.
