Análisis de la capacidad antioxidante del extracto hidroalcohólico en brotes de Scoparia dulcis mediante las técnicas de DPPH y ABTS

Abstract

This study evaluated the antioxidant capacity and phytochemical profile of extracts in growth of Scoparia dulcis, a medicinal plant known for its therapeutic properties in traditional medicine. Eight extracts were prepared using different solvents (hydroalcoholic, ethanol, methanol and ethanol/methanol combinations) and their antioxidant capacity was evaluated using the DPPH and ABTS methods. The results showed that the hydroalcoholic extract had the highest antioxidant capacity, followed by the methanolic extract and the ethanolic extract. Phytochemical analysis revealed the presence of several secondary metabolites such as alkaloids, lactones, tannins, phenols, flavonoids, coumarins and carbohydrates, known for their potential health benefits. The correlation between the DPPH and ABTS methods was moderate to strong, demonstrating that both are effective in assessing the antioxidant capacity of the extracts. Among the solvents used, hydroalcoholic extracts proved to be the most effective in extracting compounds with high antioxidant activity, reaching 93% in leaves and 98% in stems of Scoparia dulcis, which is comparable to plant extracts for their antioxidant properties. known for their oxidative activity. such as olives and thyme. These findings highlight the potential of the species as a promising source of antioxidants and bioactive compounds, which may have significant implications for use in traditional medicine and pharmaceuticals. The study also contributes to the understanding of the chemical composition of the plant and its therapeutic potential and shows that biotechnology can be used to increase the yield and efficacy of its extracts. Overall, this study reinforces the idea that hydroalcoholic extracts are a promising opportunity for the development of new natural products with antioxidant properties and other therapeutic applications.
