“…Extraction efficiency is largely influenced by factors such as solvent type and concentration and its interaction with the bio‐matrix. Methanol and ethanol are commonly selected solvents for the extraction of polyphenols from plants due to their polar nature and high boiling points . Although methanol has been reported to yield a greater extraction efficiency for TPC, its toxicity poses health risks in food grade applications .…”

“…Methanol and ethanol are commonly selected solvents for the extraction of polyphenols from plants due to their polar nature and high boiling points. [15] Although methanol has been reported to yield a greater extraction efficiency for TPC, its toxicity poses health risks in food grade applications. [12] Unlike methanol, ethanol is a GRAS solvent, hence, is preferred when the extracted phytochemical is to be used for nutraceutical or food grade applications.…”

Yellow European Plums (YEPs) are a rich source of phenolic compounds and antioxidants, which can be obtained using microwave‐assisted extraction (MAE). During this study, two MAE experiments were performed to optimize MAE extraction parameters and the MAE process using YEPs. The first experiment was to determine the influence of independent variables such as solvent concentration (20, 60, and 100 %) and solid‐to‐solvent ratio (0.05, 0.1, and 0.15 g/mL), on the yield of total phenolic content (TPC) and antioxidant activity (1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) and ferric ion reducing antioxidant power (FRAP)), for ethanol and methanol, during MAE. Using a response surface methodology, the optimized extraction parameters for MAE were then found to be 60 % ethanol at a solid‐to‐solvent ratio of 0.1 g/mL. Using the optimized parameters from the first experiment, the second experiment evaluated the effect of microwave temperature (50, 60, 70 °C) and duration (5, 10, and 15 min) on TPC, DPPH, and FRAP, using a face‐centered central composite design. Individual phenolic compounds, including ascorbic acid, neochlorogenic acid, and chlorogenic acid, were quantified using high performance liquid chromatography. In the second experiment, it was observed that time and temperature had a significant (p ≤ 0.05) effect on the extraction of phenolic compounds from four genotypes of YEPs. However, due to their diverse phenolic composition, there was not one optimal operating time and temperature suitable for all genotypes.

“…Los fitofenoles son ampliamente conocidos por los efectos bené-ficos que tienen en la salud, debido a que son antioxidantes potenciales, capaces de romper la cadena de propagación de los radicales libres, mediante la donación de un átomo de hidrógeno [2]. De esta manera, los fitofenoles pueden actuar como anticancerígenos, antidiabéticos, antibacterianos, protectores contra trastornos cardiovasculares y de daño hepá-tico [3]. Por lo anterior, la industria farmacéutica y alimentaria tiene gran interés en este tipo de compuestos para el desarrollo de nutraceúticos de tipo suplemento dietético (ej.…”

“…La mayoría de estudios relacionados con compuestos bioactivos como los fenoles, se enfocan en la caracterización, cuantificación, extracción y estudios biomédicos in vivo o in vitro [3,10]. Con la finalidad de iniciar estudios en los residuos de uva generados en Colombia, el presente documento tiene como objetivo evaluar la caracterización química de residuos generados en el cultivo y en la producción de pulpa de uva Isabella (Vitis labrusca), en términos de compuestos fenólicos totales y capacidad antioxidante.…”
