Resumo: | Medicinal plants have played an essential role in the development of human culture. Today, the contribution of plants in industries such as fine chemicals, cosmetics, pharmaceuticals, drugs, and industrial raw materials is remarkable. Recent studies have shown that plants have constituents with functional properties that effectively treat and prevent chronic degenerative diseases. Based on the importance of medicinal plants, this study aimed to quantify the total phenolic content and antioxidant activity of 10 medicinal plants. The phenolic content was quantified using the Swain and Hillis method with a Folin-Ciocalteau reagent, while the antioxidant activity was determined using a 2,2-diphenyl-1-picrylhydrazyl (DPPH) reagent. The samples were dried in a circulating air incubator at 60 ºC for 48 h before phenolic extraction. The compounds were extracted with 50% v/v ethanol, 50% v/v acetone, and distilled water. The results of this study showed that 80% of the plants analyzed had similar phenolic contents that were not statistically different, with an average content of 4.864 mg GAE g-1. The antioxidant activity ranged from 30% to 75%. The ability to scavenge free radicals was expressed as the percentage of inhibition of the oxidation of the radical. In addition, no significant differences were observed in the yield obtained from the extraction solvents, 50% v/v ethanol and 50% v/v acetone, used in this study. |

Hoy, el aporte de las platas es notable en la química fina, cosmética, farmacéutica, medicamentos y materias primas industriales. Estudios recientes han demostrado que las plantas tienen constituyentes con propriedades funcionales que son eficaces en el tratamiento y prevención de enfermedades crónico-degenerativas. Basado en la importancia de las plantas medicinales, este estudio tuvo como objetivo cuantificar el contenido fenólico total y la actividad antioxidante de 10 plantas medicinales. El contenido fenólico se cuantificó por el método de Swain y Hillis con el reactivo de Folin-Ciocalteau, mientras que la actividad antioxidante se determinó con el reactivo 2,2-difenil-1-picrilhidrazilo (DPPH). Las muestras se secaron en una estufa con circulación de aire a 60ºC durante 48 horas, antes de extraer los fenoles. Los compuestos se extrajeron con etanol al 50% v/v, acetona al 50% v/v y agua destilada. Los resultados de este estudio revelaron que el 80% de las plantas analizadas presentaron contenidos similares de fenoles que no difirieron estadísticamente, con un promedio de 4.864 mg EAG g-1, la actividad antioxidante varió entre 30 y 75%. La capacidad de capturar radicales libres se expresó como el porcentaje de inhibición de la oxidación de radicales. Además, no se observaron diferencias significativas en el rendimiento obtenido con los solventes de extracción, 50% v/v etanol y 50% v/v acetona, utilizados en este estudio.As plantas medicinais têm desempenhado um papel essencial no desenvolvimento da cultura humana.
