ABSTRACT
The composition of essential oil (EO) from Schinus latifolius obtained by hydro distillation of dry leaves was analyzed using gas chromatography (GC-FID) and gas chromatography/mass spectroscopy (GC/MS). The insecticidal effect of the oil on 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 0.5 and 1 h was determined at 26+/-1°C. The essential oil from Schinus latifolius showed significant insecticidal properties [LC50 = 31.98 mg/dm3 (0.5 h) and LC50 = 19.20 mg/dm3 (1 h)]. According to GC-FID and GC/MS analysis a total of 54 compounds were identified accounting for 99.45 percent of the EO, with limonene (50.23 percent); α-pinene (15.01percent); beta-pinene (11.81 percent); sabinene (4.71 percent) and α-thujene (2.18 percent) as the main components. The EO from Schinus latifolius appears promising as a natural insecticide against houseflies. The composition of the Schinus latifolius essential oil reported in this study is different to that reported in other publications. The most important characteristic is the high content of limonene (50.23 percent), which can be attributed to the time of year and the geographic location of the sampled plants.
RESUMEN
La composición del aceite esencial (AE), obtenido por hidrodestilación de hojas secas de Schinus latifolius se analizó mediante cromatografía de gases (CG-FID) 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 0,5 y 1 hora se determinó a 26 +/- 1ºC. El aceite esencial de Schinus latifolius mostró un buen efecto insecticida [DL50 = 31,98 mg/dm3 (0,5 h) y DL50 = 19,20 mg/dm3 (1 h)]. De acuerdo con los análisis de GC-FID y CG/EM, un total de 54 compuestos fueron identificados lo que representa el 99.45 por ciento del AE, siendo limoneno (50.23 por ciento); α-pineno (15.01 por ciento); beta-pineno (11.81 por ciento); sabineno (4.71 por ciento) y α-tujeno (2.18 por ciento) los componentes principales del AE. El AE de Schinus latifolius parece prometedor como un insecticida natural contra la mosca doméstica. La composición del aceite esencial de Schinus latifolius encontrado en este trabajo es diferente al informado en otras publicaciones. La característica mas importante es el alto contenido de limoneno (50.23 por ciento), que podría atribuirse a la época del año y la ubicación geográfica de las plantas recolectadas.
