dc.description.abstract | 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 detection, and quantified by using the
corresponding external standard calibration plot, in a 16-min run. The validation was realized calculating
the repeatability, the reproducibility and the limits of detection (LOD) and quantification (LOQ), from
standards solutions. The limits of detection and quantification were in the range of 0.16–1.09 and
0.52–3.63 mg/L, respectively, and good repeatability (R.S.D. values o1.5%) and reproducibility (R.S.D.
values o5.5%) were found. Results confirmed that the method is effective and suitable for determination
of phenolic compounds in winemaking by-products. Seeds, skins, stems and pomaces exhibited a
different qualitative and quantitative phenolic profile and different antioxidant activities. | es |
