ABSTRACT

Objetivos. Evaluar el efecto antioxidante del extracto hidroalcohólico de Calceolaria engleriana Kraenzl "wawillay" in vivo mediante el uso de ratones con lesión hepática inducida por tetracloruro de carbono (CCL4). Materiales y métodos. Estudio experimental. Se utilizó cuatro grupos de seis ratones albinos Mus musculus - cepa Balb/c/CNPB: un grupo blanco, un grupo control que recibió vitamina E (Vitesol® E 400 U.I) y dos grupos a los que se les administró extracto hidroalcohólico de Calceolaria engleriana Kraenzl "wawillay" en dosis de 50 y 300 mg/kg. Para la evaluación del efecto antioxidante in vivo se sometió a los ratones a un modelo experimental de hepatotoxicidad por tetracloruro de carbono (CCL4) antes y durante las intervenciones. Mediante la reacción del ácido tiobarbitúrico se cuantificó el malonaldialdehido (MDA) formado y se calculó el porcentaje de inhibición de peroxidación lipídica (POL) con el que se establecieron diferencias por grupos. Resultados. El tamizaje fitoquímico mostro la presencia muy abundante de flavonoides. Los porcentajes de inhibición de la POL obtenidos fueron de un 22 y 45%, para las dosis de 50 y 300 mg/kg del extracto hidroalcohólico. Si bien se encontraron diferencias significativas en la comparación entre grupos (p>0,05), las intervenciones experimentales no superaron los resultados del grupo control con vitamina E (60%). Conclusiones. En las condiciones experimentales, el extracto hidroalcohólico de Calceolaria engleriana Kraenz "wawillay" a dosis de 50 y 300 mg/kg presenta actividad antioxidante, siendo esta aun menor a la mostrada por el estándar (vitamina E).


Objetive. To evaluate the in vivo antioxidant effect of Calceolaria engleriana Kraenzl "wawillay" hydro-alcoholic extract through the use of mice with hepatic injury induced by carbon tetrachloride (CCL4). Materials and methods. An experimental study. Four groups of 6 albino Mus musculus ­ strain Balb/c/CNPB mice were used: a no-intervention group; a control group, which received Vitamin E (VITESOL® E 400 U.I); which Calceolaria engleriana Kraenzl "wawillay" hydro-alcoholic extract in doses of 50 mg/kg and 300 mg/kg of the extract. To evaluate in vivo antioxidant effect, mice were subjected to an experimental model of hepatotoxicity by carbon tetrachloride (CCL4) before and during experimental interventions. Through the thiobarbituric acid reaction, the malonalmaldehyde (MDA) formed was quantified and the percentage inhibition of lipid peroxidation (POL) was calculated. With this data, statistical differences were established by groups. Results. Phytochemicalscreening showed "very abundant" presence of flavonoids. The percentages of POL inhibition obtained were 22% and 45%, for the doses of 50 mg/kg and 300 mg/kg of hydro-alcoholic extract. Although significant differences were found in the comparison between groups (p> 0.05), the experimental interventions did not surpass the results of control group intervened with Vitamin E (60%). Conclusions. Under the experimental conditions, the Calceolaria engleriana Kraenz "wawillay" hydro-alcoholic extract (at doses of 50 mg/kg and 300 mg/kg) has antioxidant activity, but the effect found were lower than the standard (Vitamin E).
