dc.description.abstractContext: In the Valley of Ica-Peru, the seeds of the fruit of Vitis vinifera L. (grape) are residues from the Pisco Industry, and due to their bioactive compounds, they can represent a new economic and sustainable activity for the population of the mentioned Valley. Aims: To characterize polyunsaturated fatty acids from the seeds of the fruit of Vitis vinifera L. (grape) from the Ica Valley, Peru and determine the antioxidant activity in vitro. Methods: The oil from five grape varieties (Quebranta, Moscatel, Torontel, Mollar, and Italia) was obtained by ethereal extraction with ultrasound. The profile of fatty acids was characterized by gas chromatography with a flame ionization detector (GC-FID). The total polyphenolic content was determined by the Folin-Ciocalteu method and antioxidant activity by two in vitro methods. Results: The values obtained from the 5 grape varieties are presented in a range: total polyphenolic content (TPC: 0.59-154 mg GAE/g); linoleic acid content (69.90-71.87%), oleic acid (18.35-19.90%) and others in a lower percentage (p>0.05). Antioxidant activity: DPPH IC50 38.30-48.43 µL; FRAP 0.49-0.77 μg TEAC/g. TPC/DPPH and TPC/FRAP were significantly different (p<0.05), except for the Mollar TPC/FRAP variety (p>0.05). Conclusions: The oils from the seeds of the Vitis vinifera fruit (grapes) that are residues from the production of Pisco present physicochemical characteristics of oils of high nutritional value with a predominance of polyunsaturated fatty acids and potential antioxidant activity. .en_US

Objetivos: Caracterizar ácidos grasos poliinsaturados de las semillas del fruto de Vitis vinífera L. (uva) procedentes del valle de Ica, Perú y determinar la actividad antioxidante in vitro. Métodos: El aceite de cinco variedades de uvas (Quebranta, Moscatel, Torontel, Mollar e Italia) se obtuvo por extracción etérea con ultrasonido. Por cromatografía de gases con detector de ionización de llama (CG-FID) se caracterizó el perfil de los ácidos grasos. El contenido polifenólico total se determinó por el método Folin-Ciocalteu; actividad antioxidante por dos métodos in vitro. Resultados: Los valores obtenidos de las 5 variedades de uvas se presentan en un rango: contenido polifenólico total (CPT: 0.59-154 mg GAE/g); contenido de ácido linoleico (69.90-71.87 %), oleico (18.35-19.90 %) y otros en menor porcentaje (p>0.05). Actividad antioxidante: DPPH IC50 38.30-48.43 µL; FRAP 0.49-0.77μg TEAC/g. CPT/DPPH y CPT/FRAP significativamente diferentes (p<0.05), excepto para la variedad Mollar CPT/FRAP (p>0.05). Conclusiones: Los aceites de las semillas del fruto Vitis vinifera (uvas) que son residuos de la producción de Pisco presentan características fisicoquímicas de aceites de alto valor nutricional con predominio de ácidos grasos poliinsaturados y una potencial actividad antioxidante.es_PE
