Antioxidants in Plants: A Valorization Potential Emphasizing the Need for the Conservation of Plant Biodiversity in Cuba

Abstract: Plants are phytochemical hubs containing antioxidants, essential for normal plant functioning and adaptation to environmental cues and delivering beneficial properties for human health. Therefore, knowledge on the antioxidant potential of different plant species and their nutraceutical and pharmaceutical properties is of utmost importance. Exploring this scientific research field provides fundamental clues on (1) plant stress responses and their adaptive evolution to harsh environmental conditions and (2) (new… Show more

“…Cuba is recognized as the island with the highest degree of endemism in the West-Indies, including more than half of its plant species [ 3 ]. Since plants in Cuba are frequently subjected to harsh environmental conditions (e.g., high temperature, drought, high levels of sunlight, salinity, nutrient-poor soil conditions), combined with the fact that the Cuban flora is pharmacologically and chemically under-investigated [ 4 ], the development of conservation strategies to preserve the plant species of the island is necessary.…”

“…En nuestra investigación en los cinco lotes estudiados se obtuvo la presencia de fenoles, coincidiendo con lo planteado en la literatura que reporta que la caléndula puede ser cultivada en todo el año, no presentando diferencias significativas en cuanto a su composición de metabolitos secundarios (Lastra y Piquet, 1999). La cantidad de estos metabolitos para el extracto blando obtenido a partir de las flores colectadas en el mes de octubre del 2017, difiere estadísticamente con respecto a las recolectadas en el mes de febrero del 2018, lo que pudo deberse a que existe una variación en el contenido de metabolitos activos en matrices de origen natural, que puede ser influenciada por diversos factores que dependen de la naturaleza de la planta (droga utilizada, variación natural entre plantas, quimio-variedad); de los factores como la siembra, la cosecha, almacenamiento y de los factores tecnológicos, que se encuentran relacionados con los procesos de secado y extracción (Muñoz ,2014;Llauradó et al, 2020).…”

“…), a los que se le atribuyen propiedades farmacológicas de interés, dentro de las que se encuentran principalmente la antiinflamatoria, antiséptica, cicatrizante y antioxidante de la gran mayoría de las plantas (Rotta et al, 2017). No obstante, la calidad y cantidad producida de estos compuestos por las plantas medicinales está muy condicionada a factores bióticos y abióticos relativos a los lugares donde se cultivan y cosechan (Llauradó et al, 2020).…”
