ABSTRACT
The chemical constituents and insecticidal activity of essential oil obtained by hydrodistillation of the leaves of Paullinia pinnata Linn (Sapindaceae) are being reported. The essential oil were analysed by using gas chromatography (GC) and gas chromatography coupled with mass spectrometry (GC-MS). Different concentrations (50, 100, 150, 200 and 250 mg/mL) of P. pinnata essential oil prepared separately and diluted in dimethyl sulfoxide (DMSO) were tested on the maize weevil, Sitophilus zeamais. The main constituents of the oil were pentadecanoic acid (17.9%), isoaromadendrene epoxide (11.5%) and wine lactone (11.2%). Other significant compounds of the essential oil were eremophilene (6.9%) and phytol (6.2%). The essential oil displayed 100% mortality (fumigant toxicity) against S. zeamais adults at tested concentration of 150 mg/mL with lethal concentrations (LC50) of 51.87 mg/mL air. This is the first report on the chemical constituents and insecticidal activity of essential oil of P. pinnata and may be explore as a potential natural herbal plant for the control of insect pest.
RESUMEN
Se informan los componentes químicos y la actividad insecticida del aceite esencial obtenido por hidrodestilación de las hojas de Paullinia pinnata Linn (Sapindaceae). El aceite esencial se analizó mediante cromatografía de gases (GC) y cromatografía de gases acoplada con espectrometría de masas (GC-MS). Se ensayaron diferentes concentraciones (50, 100, 150, 200 y 250 mg/ml) de aceite esencial de P. pinnata preparado separadamente y diluido en dimetilsulfóxido (DMSO) en el gorgojo de maíz, Sitophilus zeamais. Los componentes principales del aceite fueron ácido pentadecanoico (17,9%), isoaromadendreno epóxido (11,5%) y vino lactona (11,2%). Otros compuestos significativos del aceite esencial fueron eremophilene (6,9%) y phytol (6,2%). El aceite esencial mostró una mortalidad del 100% (toxicidad fumigante) contra los adultos de S. zeamais a una concentración de 150 mg/ml con concentraciones letales (CL50) de 51,87 mg/ml de aire. Este es el primer informe sobre la composición del aceite esencial de P. pinnata y su actividad insecticida. Puede ser explorado como una potencial planta herbácea natural para el control de la plaga de insectos.
