ABSTRACT
In this study, we investigated the main constituent, the predominant class and biological activity of the essential oil extracted from the leaves of Pimenta dioica and the pattern of the major constituent against larvae in the third stage of Aedes aegypti. For this reason, we extracted the oil by hydrodistillation, identified its components by gas chromatography coupled with mass spectrometry (GC/MS) and calculated the lethal concentration (LC50) of the larvicidal activity using the Reed-Muench method. The results show that the oil consists mainly of eugenol, in which the phenylpropanoid class predominated and the lethal concentration, LC50, was 38.86 µg mL-1at a confidence level of 2.25 µg mL-1, while the eugenol standard presented LC5079.75 µg mL-1at a confidence level of 2.10 µg mL-1. Given the facts, we conclude that the oil is more active than the standard and that it has the potential to replace chemical larvicides.
RESUMEN
En este estudio, investigamos el constituyente principal, la clase predominante y la actividad biológica del aceite esencial extraído de las hojas de Pimenta dioica y el patrón del constituyente principal contra las larvas en la tercera etapa de Aedes aegypti. Por este motivo, extrajimos el aceite por hidrodestilación, identificamos sus componentes mediante cromatografía de gases acoplada a espectrometría de masas (GC/MS) y calculamos la concentración letal (CL50) de la actividad larvicida mediante el método Reed-Muench. Los resultados muestran que el aceite está constituido principalmente por eugenol, en el que predominó la clase fenilpropanoide y la concentración letal, CL50, fue de 38,86 µg.mL-1 a un nivel de confianza de 2,25 µg.mL-1, mientras que el estándar de eugenol presentó CL50 79,75 µg.mL -1 a un nivel de confianza de 2,10 µg.mL-1. Dados los hechos, concluimos que el aceite es más activo que el estándar y que tiene el potencial de reemplazar los larvicidas químicos.
