Journal ArticleDOI
The relative antioxidant activities of plant-derived polyphenolic flavonoids
TL;DR: The relative antioxidant activities, against radicals generated in the aqueous phase, of a range of plant-derived polyphenolic flavonoids, constituents of fruit, vegetables, tea and wine, have been assessed and compounds such as quercetin and cyanidin have antioxidant potentials four times that of Trolox, the vitamin E analogue.
Journal ArticleDOI
The biosynthesis and nutritional uses of carotenoids.
Paul D. Fraser,Peter M. Bramley +1 more
TL;DR: The aim of this article is to review the current understanding of carotenoid formation, to explain the perceived benefits ofcarotenoids in the diet and review the efforts that have been made to increase carotanoids in certain crop plants.
Journal ArticleDOI
Antioxidant activities of carotenes and xanthophylls
TL;DR: The results show that the relative abilities of the carotenoids to scavenge the ABTS·+ radical cation are influenced by the presence of functional groups with increasing polarities, such as carbonyl and hydroxyl groups, in the terminal rings, as well as by the number of conjugated double bonds.
Journal ArticleDOI
Chemical derivatization and mass spectral libraries in metabolic profiling by GC/MS and LC/MS/MS
John M. Halket,Daniel Waterman,Anna Przyborowska,Raj K. P. Patel,Paul D. Fraser,Peter M. Bramley +5 more
TL;DR: The potential of derivatization for metabolic profiling in LC/MS is demonstrated by the enhanced analysis of plant extracts, including the potential to measure volatile acids such as formic acid, difficult to achieve by GC/MS.
Journal ArticleDOI
Carotenoid Biosynthesis during Tomato Fruit Development (Evidence for Tissue-Specific Gene Expression)
TL;DR: The results suggest that transcription of Psy and Pds is regulated developmentally, with expression being considerably elevated in chromoplast-containing tissues, and lends support to the hypothesis of divergent genes encoding these enzymes.
