Quince (Cydonia oblonga Miller) fruit (pulp, peel, and seed) and jam: Antioxidant activity
Branca M. Silva,Paula B. Andrade,Patrícia Valentão,Federico Ferreres,Rosa M. Seabra,Margarida A. Ferreira +5 more
TL;DR: The evaluation of the antioxidant activity of methanolic extracts showed that peel extract was the one presenting the highest antioxidant capacity, which seems to indicate that the phenolic fraction gives a higher contribution for the antioxidant potential of quince fruit and jam.
Journal ArticleDOI

Ana Ferreira da Vinha,Federico Ferreres,Branca M. Silva,Patrícia Valentão,Ana Cristina Gonçalves,José Alberto Pereira,M. Beatriz P.P. Oliveira,Rosa M. Seabra,Paula B. Andrade +8 more
TL;DR: In this paper, the phenolic compounds present in 29 samples of olive fruits were analysed by reversed-phase HPLC/DAD and/or HPLC-DAD/ESI-MS/MS.
Journal ArticleDOI
Approach to the study of C‐glycosyl flavones by ion trap HPLC‐PAD‐ESI/MS/MS: application to seeds of quince (Cydonia oblonga)
TL;DR: Ion trap HPLC-PAD-ESI/MS/MS has been used to study C-glycosyl flavones in quince seeds and deductions were made about the nature of the sugar units and the positions of C- Glycosylation.
