ABSTRACT
The composition of the essential oil (EO) obtained by hydro distillation from dry leaves of Peumus boldus was analyzed using gas chromatography (GC) and gas chromatography/mass spectroscopy (GC/MS). The insecticidal activity of the oil against the house fly Musca domestica was evaluated by placing flies in a sealed glass jar containing a piece of EO-treated cotton yarn. The dose necessary to kill 50 percent of flies (LC50) in 1 h was determined at 26 +/-1°C. The essential oil from Peumus boldus showed potent insecticidal properties (LC50 = 6.26 mg/dm3). According to GC and GC/MS analysis, 1,8-cineol (36.72 percent); p-cymene (26.79 percent); ascaridol (6.25 percent); sabinene (5.10 percent); 4-terpineol (4.39 percent); beta-pinene (4.16 percent) and limonene (2.68 percent) were the principal components of the EO. The EO from Peumus boldus seems promising as a natural insecticide against houseflies. The peumus boldus essential oil reported in this paper is different to that reported in other publications. .The most important differences are the low content of ascaridol and the high content of both 1,8-cineol and p-cimene which can be attributed to the time of year and the geographic location of the samples plant.
RESUMEN
La composición del aceite esencial (AE), obtenido por hidrodestilación de hojas secas de Peumus boldus se analizó mediante cromatografía de gases (CG) y cromatografía de gases / espectrometría de masas (CG / EM). La actividad insecticida del aceite contra la mosca doméstica, Musca domestica se evaluó colocando las moscas en un frasco de vidrio sellado con un trozo de hilo de algodón tratado con diferentes cantidades de AE. La dosis necesaria para matar el 50 por ciento de las moscas (LC50) en 1 hora se determinó a 26 +/- 1ºC. El aceite esencial de Peumus boldus mostró potentes propiedades insecticidas (LC50= 6.26 mg/dm3). De acuerdo con los análisis de GC y CG / EM, 1,8-cineol (36,72 por ciento), p-cimeno (26.79 por ciento); ascaridol (6,25 por ciento); sabineno (5.10 por ciento), 4-terpineol (4,39 por ciento), beta-pineno (4,16 por ciento) y limoneno (2,68 por ciento) fueron los componentes principales del AE. El AE de Peumus boldus parece prometedor como un insecticida natural contra moscas. La composición del aceite esencial de Peumus boldus encontrado en este trabajo es diferente a lo reportado en otras publicaciones. Las diferencias más importantes son el bajo contenido de ascaridol y el alto contenido de ambos 1,8-cineol y p-cimeno que puede atribuirse a la época del año y la ubicación geográfica de las plantas recolectadas.
