ABSTRACT
Vitex gardneriana Schauer (Lamiaceae) popularly known as "jaramataia", is a shrub commonly found in caatinga biome located in Northeast Brazil. In folk medicine, its leaves have been used as analgesic and anti-inflammatory agents. The chemical composition of the essential oil from leaves obtained by hydrodistillation was analyzed and identified by GC-MS and GC-FID and showing a total of 26 constituents (95.9%) being 2 monoterpenes (0.4%) and 24 sesquiterpenes (95.4%). The main constituents identified were cis-calamenene (29.7%), 6,9-guaiadiene (14.5%) and caryophyllene oxide (14.0%). The essential oil has been demonstrated high larvicidal activity against Aedes aegypti (LC50 = 28.0 µg/mL). In the evaluation of the bioassay with Artemia salina the essential oil showed LC50 = 98.11 µg/mL. In addition, the essential oil did not show cytotoxicity (IC50 > 2.50 mg/mL) by the hemolysis assay.
RESUMEN
Vitex gardneriana Schauer (Lamiaceae) popularmente conocido como "jaramataia", es un arbusto que se encuentra comuÌnmente en el bioma de caatinga ubicado en el noreste de Brasil. En medicina popular, sus hojas se han utilizado como analgeÌsicos y agentes antiinflamatorios. La composicioÌn quiÌmica de los aceites esenciales de las hojas obtenidas por hidrodestilacioÌn fue analizada e identificada por GC-MS y GC-FID y mostrando un total de 26 constituyentes (95.9%) siendo 2 monoterpenos (0.4%) y 24 sesquiterpenos (95.4%). Los componentes principales fueron cis-calamenene (29.7%), 6,9-guaiadiene (14.5%) y caryophyllene oxide (14.0%). El aceite esencial ha demostrado una alta actividad larvicida contra Aedes aegypti (CL50 = 28.0 µg/mL). En la evaluacioÌn del bioensayo con Artemia salina, el aceite esencial demostroÌ CL50 = 98.11 µg/mL. AdemaÌs, el aceite esencial no mostroÌ citotoxicidad (IC50 > 2.5 mg / mL) mediante el ensayo de hemoÌlisis.
