Molecular design and experimental evaluation of Jatropha gossypifolia

Problem: Recent studies have demonstrated the role of free radicals and reactive oxygen species and their link to different pathological processes including cancer, developing multiple herbal formulations for this purpose. One of the plants that has increased in research interest in recent years, due to the multiplicity of uses attributed to it, is Jatropha gossypifolia L.
Objective: to determine the antioxidant activity of Jatropha gossypifolia through prediction and experimental evaluation.

Methods: First, an automated system based on regression trees was developed for the prediction of antioxidant activity by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay in Jatropha gossypifolia. Then three extracts (hydroalcoholic, methanolic and ethyl acetate) were prepared and evaluated qualitatively through phytochemical screening and quantitatively through their phenolic and total flavonoid content. Their antioxidant activity was determined through the DPPH assay.

Results: The automated system allowed tree-based virtual screening and identification of compounds with potential antioxidant activity by DPPH, which are mostly flavonoids. Phytochemical screening showed the presence of alkaloids, tannins, flavonoids, coumarins, quinones, triterpenes, steroids, and anthocyanins. The quantified phenols and flavonoids were higher for the hydroalcoholic extract. The in vitro antioxidant activity was experimentally corroborated by DPPH of Jatropha gossypifolia leaves, with the hydroalcoholic extract being the one with the greatest antioxidant power. Finally, the antioxidant activity demonstrated for the species is related to the presence of flavonoids and other phenolic compounds.

Conclusions: The results obtained support the popular use of the plant and open the way towards the development of new phytopharmaceuticals in the pharmaceutical industry. 

Problemática: Estudios recientes han demostrado el papel de los radicales libres y las especies reactivas del oxígeno y su vínculo a distintos procesos patológicos incluyendo el cáncer, desarrollándose múltiples formulaciones herbarias con este fin. Una de las plantas que ha aumentado en interés investigativo en los últimos años, por la multiplicidad de usos que se le atribuyen es Jatropha gossypifolia L.

Objetivo: Determinar la actividad antioxidante de Jatropha gossypifolia mediante predicción y evaluación experimental.

Métodos: Se desarrolló un sistema automatizado basado en árboles de regresión para la predicción de la actividad antioxidante por ensayo 2,2- difenil-1- picrilhidracilo (DPPH) en Jatropha gossypifolia. Se elaboraron tres extractos (hidroalcohólico, metanólico y de acetato de etilo) evaluados cualitativamente a través del tamizaje fitoquímico y cuantitativamente mediante su contenido de fenoles y flavonoides totales.

Resultados: El sistema automatizado permitió el cribado virtual basado en árboles y la identificación de compuestos con potencial actividad antioxidante por DPPH, los cuales son mayoritariamente flavonoides. El Tamizaje fitoquímico mostró presencia de alcaloides, taninos, flavonoides, coumarinas, quinonas, triterpenos, esteroides, y antocianinas. Los fenoles y flavonoides cuantificados fueron superiores para el extracto hidroalcohólico. Se corroboró experimentalmente la actividad antioxidante in vitro por DPPH de las hojas de Jatropha gossypifolia, resultando el extracto hidroalcohólico el de mayor poder antioxidante. Finalmente, la actividad antioxidante demostrada para la especie se relaciona con la presencia de flavonoides y otros compuestos fenólicos.

Conclusiones: Los resultados obtenidos avalan el uso popular de la planta y abren el camino hacia el desarrollo de nuevos fitofármacos en la industria farmacéutica.
