Detailed Phenolic Composition of White Grape by-products by RRLC/MS and Measurement of the Antioxidant Activity

Jara Palacios, Mª José Hernanz Vila, María Dolores González Manzano, Susana

The development and validation of a rapid method of RRLC has been carried out to determine the phenolic composition of winemaking by-products (pomaces, seeds, skins and stems). Thirty-one phenolic compounds belonging to three groups (flavanols, flavonols and phenolic acids) have been identified by use of standards and mass spectrometric...

Study of Zalema Grape Pomace: Phenolic Composition and Biological Effects in Caenorhabditis Elegans

Jara Palacios, Mª José González Manzano, Susana Escudero Gilete, María Luisa

The phenolic composition of the extractable fraction of Zalema grape pomace has been analyzed by HPLC-DAD-MS and consisted of mainly flavanols and flavonols (122.75 and 23.11 mg/100 g dry pomace, respectively). The antioxidant activity has been determined by in vitro FRAP, ABTS, and ORAC assays (11.7, 34.9, and 63.6 mmol of Trolox equivalents...
