Estudios de las propiedades medicinales de extracto total y distintas fracciones de Ligaria cuneifolia (R. et P.) Tiegh (Loranthaceae).

Abstract

Ligaria cuneifolia (Lc) (R. et P.) Tiegh. (Loranthaceae), popularmente conocida como “muérdago criollo”, “liga” o “liguilla”, es una especie hemiparásita, que se encuentra en el centro y norte de Argentina. En medicina tradicional es utilizada para disminuir la presión arterial y el colesterol. Basándonos en las observaciones empíricas, planteamos como objetivo demostrar científicamente que Ligaria cuneifolia tiene propiedades hipotensoras e hipocolesterolémicas. En ratas Wistar machos adultas alimentadas con dieta normal, enriquecida en colesterol y en hiperlipémicas (alimentadas con High Fat Diet), demostramos que el tratamiento por vía intraperitoneal con una fracción enriquecida en Proantocianidinas extraídas de Lc (PLc) produce disminución del 40% del colesterol plasmático (Co) debido al aumento de la velocidad de excreción biliar de sales biliares, así como disminución de triglicéridos y LDLCo, sin producir cambios en la fluidez de la sangre. Evaluamos el efecto vasoactivo de PLc in vitro en anillos de aorta aislada de ratas determinando su tensión isométrica, presentando efecto vasodilatador dependiente de endotelio, ya que la remoción mecánica del mismo anula completamente la relajación. El tratamiento con infusión de extracto liofilizado de hojas y tallos de Lc ingerida tres veces por semana durante dos meses por pacientes hipercolesterolémicos de ambos sexos (edad: 50 ± 15 años), permitió observar descenso en los niveles Co y LDLCo, sin mostrar alteraciones en la fluidez de la sangre ni en la funcion hepático. Conclusión: Ligaria cuneifolia sería una potencial herramienta en la prevención de enfermedades cardiovasculares, por disminuir el Colesterol plasmático y presentar un marcado efecto hipotensor.
