ABSTRACT

Fundamentos: Boldoa purpurascens Cav (nitro blanco) ha sido utilizada tradicionalmente como diurética en Cuba, sin embargo, no cuenta con los estudios toxicológicos preclínicos establecidos. Objetivos: determinar la toxicidad aguda de un extracto acuoso liofilizado de hojas secas de B. purpurascens. Métodos: se realizó un estudio preclínico mediante el método de sube y baja (UDP), el grupo experimental estuvo conformado por 5 ratas hembras de la línea Sprague Dawley. Se administró una dosis límite diaria de 2 000 mg/kg. Se realizaron observaciones sistemáticas durante el transcurso del experimento y el día 14 posadministración se procedió a la eutanasia de los animales. Resultados: el peso corporal se comportó acorde a la curva de crecimiento de la especie, sin evidencia de signos tóxicos ni muerte de ningún animal. El estudio anatomopatológico macroscópico de los órganos no mostró alteraciones. Conclusiones: la dosis tóxica del extracto estudiado es superior a 2 000 mg/kg y clasifica como no tóxico.


Foundations: Boldoa purpurascens Cav (nitro blanco) has been traditionally used as a diuretic in Cuba; however, the established preclinical toxicological studies have not been conducted yet. Objectives: to determine acute toxicity in a freeze-dried aqueous extract form dry leaves of B. Purpurascens. Methods: a preclinical study was undertaken by the up and down procedure. The experimental group was composed of 5 Sprague Dawley female rats. A daily limited dose of 2 000 mg/kg was administered. Systematic observations were made during the experiment and on the 14th postadministration day, the euthanasia of the animals was performed. Results: the body weight behaved according to the growth curve of the species without evidence of toxic signs or death of any animal. The macroscopic anatomopathological study of the organs showed no alterations. Conclusions: the toxic dose of the studied extract is higher than 2 000 mg/kg and classifies as non-toxic.
