This study aimed to evaluate the larvicidal activity of essential oil (EO) and nanoemulsion (O/A) of Coleus aromaticus Benth (coarse mint) leaves. In the total phenolic assay, the value of 350.86 mg EAT g-1 was quantified, being a significant result for the presence of the class in the essential oil. In the antioxidant activity assay, the IC50 of 195.39 mg L-1 was obtained for the action of C. aromaticus being classified as promising. The action of the EO as larvicidal was observed and the LC50 of 3.24 mg L-1 was determined, while for nanoemulsion a higher action was observed at 1.83 mg L-1. T...

The action of the EO as larvicidal was observed and the LC50 of 3.24 mg L-1 was determined, while for nanoemulsion a higher action was observed at 1.83 mg L-1. The results obtained allowed us to conclude that the studied EO presented larvicidal activity against the larvae of Aedes aegypti. Finally, we highlight the potential obtained for EO and nanoemulsion obtained from the species under study, and it is important to highlight that the nanoemulsion is a bioproduct formulated from the essential oil with market potential, being important in the control and combat of cases related to Aedes aegypti.
