          Abstract

          La planta conocida como "botón de plata" (Spilanthes urens Jacq) es una especie silvestre de las Antillas (Cuba, República Dominicana y Puerto Rico); en el Oriente de Cuba se utiliza por los campesinos para aliviar las dolencias dentales. El órgano de la planta empleado por los campesinos es la flor. Algunas encuestas demostraron la utilidad también de las hojas, pero no refieren indicios anestésicos, sí con el uso de las flores. Se realizó una caracterización cualitativa a las hojas y flores mediante tamizaje fitoquímico. Se encontraron distintos tipos de metabolitos: triterpenos, esteroides, cumarinas, azúcares reductores, aminoácidos libres, aminas, saponinas, flavonoides, poliurónidos y alcaloides, en ambos órganos de la planta. Se realizó una extracción de los alcaloides, obteniéndose sólidos amarillos en los dos casos, aunque en mayor cantidad para las flores. Se aplicó la Marcha Sistemática de Banford para clasificar estos alcaloides, dando positiva la prueba que clasifica al compuesto (o los compuestos) como derivados del indol. Se empleó la cromatografía de placa delgada para tener indicios del grado de pureza de los productos. Finalmente, se registraron los espectros ultravioleta-visibles para tener una idea de la presencia del anillo indólico.

          The plant known as "silver button" (Spilanthes urens Jacq) is a wild species from Las Antillas: Cuba, Dominican Republic and Puerto Rico. In the East of Cuba is used by farmers in some places to ease dental ailments. The organ of the plant used by farmers is the flower. Some surveys made to effect also demonstrated the utility of the leaves, but do not refer to anesthetic indications. However, it argues that using flowers the effect is numbing, almost anesthetic. Qualitative characterization leaves and flowers of this species by phytochemical screening were performed. Different types of metabolites are found: triterpenoids, steroids, coumarins, reducing sugars, free amino acids, amines, saponins, flavonoids, alkaloids and polyuronides. Due to the versatile properties including anesthetic, an alkaloids extracting process was carried out, and yield yellow solids but in greater quantity for the flowers. After was applied Banford Systematic March to classify these alkaloids. The result gave positive for test that classifies the compound (or compounds) as indole derivatives. Thin layer chromatography for clues to the degree of purity of the product was applied. Finally the UV-visible spectroscopy to get an idea of the presence of the indole ring spectra was recorded.
