Obtenção de Espilantol a partir das folhas de jambu (Spilanthes Acmella (L.) Murr.)

Abstract

In the search for alternative treatments to control parasitic diseases in Brazilian cattle herds has been invested in research on natural products, especially plants that have acaricide activity (ticks). The “jambu” (Spilanthes acmella (L.) Murr., native herbaceous plant of the Northern Region, belonging to Asteraceae family, is already reported in the literature as possessing insecticidal and acaricidal activity, due to the presence of an alkylamide named spilanthol. Thus, in this study used the hexane extract from leaves of Spilanthes acmella (L.) Murr., which was submitted initially to liquid-liquid partition and later for several chromatographic methods such as HPLC. Through HPLC yielded a yellow liquid, which was characterized as spilanthol after spectrometric analysis by high resolution mass spectrometry, nuclear magnetic resonance 1H and 13C (1D and 2D NMR spectroscopy) and FT-IR.
