El propósito de este estudio fue la caracterización de los componentes bioactivos, específicamente antioxidantes y polifenoles, presentes en el Clinopodium tomentosum en muestras tanto secas como húmedas. Se implementó un método de extracción asistido por ultrasonido para la obtención de principios activos. Posteriormente, se realizó la identificación y cuantificación de los compuestos obtenidos mediante los ensayos de capacidad antioxidante Ferric Reducing Antioxidant Power y Folin-Ciocalteu. Como resultado de este proceso, se observó que la extracción en materia seca proporciona un rendimiento superior, con concentraciones de 1.49 mg L-1 de polifenoles y 1.27 mg L-1 de antioxidantes, en comparación con la extracción en estado húmedo, que arrojó concentraciones de 1.39 mg L-1 de polifenoles y 1.04 mg L-1 de antioxidantes. La caracterización de la Clinopodium tomentosum ha permitido la identificación de sus componentes bioactivos, abriendo la puerta a investigaciones futuras sobre la identificación de los componentes fitoquímicos y su potencial aplicación en las industrias alimentaria y no alimentaria.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In ancient times, various plant species were used in traditional medicine due to their properties, being utilized in diverse processes, both in the food and pharmaceutical sectors. The purpose of this study was to characterize the bioactive components, specifically antioxidants and polyphenols, present in Clinopodium tomentosum in both dry and wet samples. An ultrasound-assisted extraction method was implemented to obtain the active compounds. Subsequently, the identification and quantification of the extracted compounds were performed using the FRAP (Ferric Reducing Antioxidant Power) and Folin-Ciocalteu assays. As a result of this process, it was observed that extraction from dry matter yields higher concentrations, with 1.49 mg L-1 of polyphenols and 1.27 mg L-1 of antioxidants, compared to wet extraction, which yielded concentrations of 1.39 mg L-1 of polyphenols and 1.04 mg L-1 of antioxidants. The characterization of Clinopodium tomentosum enabled the identification of its bioactive components, paving the way for future research on the identification of its phytochemical components and their potential application in both food and non-food industries.]]></p></abstract>
