FLAVONOIDES Y ACTIVIDAD ANTIOXIDANTE DE Calia secundifl ora (Ort.) Yakovlev

Abstract

La posible extinción de algunas especies no estudiadas como Calia secundiflora (Ort.) Yakovlev signifi ca la pérdida del potencial que rep- resenta el conocimiento de sus metabolitos con propiedades medicina- les y de interés agronómico. Los estudios fi toquímicos en C. secundiflora (Ortega) Yakovlev (Fabaceae) se han enfocado hacia los alcaloides, pero aún se desconoce su perfil de flavonoides. Estos metabolitos presentes en los vegetales se asocian con una capacidad antioxidante natural, y que estudios epidemiológicos han mostrado efectos benéficos para la salud humana. El objetivo de esta investigación fue cuantificar el contenido de compuestos fenólicos y flavonoides, así como identificar las estructuras de los flavonoides en hoja y evaluar el potencial antioxidante de los extractos. La actividad antioxidante se evaluó por el método de DPPH (2,2-difenil-1-picrilhidracilo) en muestras de una zona del estado de Hidalgo, México. El análisis por CL-EM permitió identificar siete glicósidos en los flavonoles quercetina, isoramnetina y kaenferol, no descritos previamente para esta especie. El contenido de compuestos fenólicos totales (8.31 ± 0.38 mg g-1 de MS) fue mayor al de flavonoides (3.08 ± 0.32 mg g-1 de MS). Estos resultados explican la actividad antioxidante (CI50 = 88.54 ± 0.15; 109.44 ± 0.48 μg mL-1) que presentaron los extractos de hoja. La identifi cación de estos fl avonoides puede contribuir a la quimiotaxonomía del género.
