Extracción, pruebas de estabilidad y análisis químico preliminar de la fracción colorante obtenido a partir del exocarpo del fruto de Renealmia Alpinia

Abstract

<div class="page" title="Page 1"><div class="section"><div class="layoutArea"><div class="column"><p><span>Del exocarpo del fruto comestible de la especie </span><span>Renealmia Alpinia, </span><span>proveniente de la Amazonía sur del Ecuador, mediante una extracción alcohólica y posterior evaporación del solvente, se obtuvo una fracción colorante de tonalidad púrpura con un rendimiento del 2,13%.A dicha fracción se la sometió a diversas pruebas para analizar su estabilidad en variadas condiciones como: pH, temperatura y su comportamiento con solventes de diversa polaridad. Para conocer anticipadamente su naturaleza química se efectuaron diversos ensayos entre los que destacamos: su espectro ultravioleta visible, su espectro infrarrojo, la cuanti cación de antocianos totales y sus per les cromatográ cos en HPLC a 520 nanómetros.Adicionalmente, se evaluó la toxicidad de la especie. </span></p></div></div></div></div>
