Thesis (MScAgric)--University of Stellenbosch, 2002.<br>ENGLISH ABSTRACT: Trials were conducted to follow colour development during the growth season of the commercial Leucadendron cultivar 'Siivan' Red', as well as the Protea cultivars 'Ivy', 'Carnival' and 'Sylvia'. HPLC analysis showed that pigments responsible for red colour in Leucadendron and Protea cultivars are anthocyanins. Initial extraction of anthocyan ins from freeze-dried and finely ground Leucadendron leaves, using 5% formic acid in methanol, resulted in the precipitation of gel-like compounds, making the extracts impossi

A systematic study on extraction of Hibiscus sabdariffa was carried out for the first time using different solvents (water, methanol, ethyl acetate and hexane) in the presence and absence of formic acid, using different extraction times and temperatures. The extracts were analysed for total phenol content, antioxidant capacity using DPPH, FRAP and TEAC assays, and total monomeric anthocyanin content. In addition, specific anthocyanins were determined using HPLC and LC-MS. The results showed the highest antioxidant capacities were obtained by extracting using water, with or without formic acid,

Abstract:

The anthocyanins, a relatively small group of pigments in the diverse flavonoid family, are largely responsible for the red-blue colouration in a large number plant species worldwide. Their occurrence in fruits and flowers seems to offer clear benefits in attracting pollinators and aiding seed dispersal, however their presence in the vacuoles of leaves remains obscure. The accumulation of anthocyanin pigments in leaves can be induced by a host of disparate environmental and anthropogenic stressors, such as UV-exposure, wounding, pathogen infection, high light, chilling, pollution, osmotic stre

Abstract:

Beneficial health effects of anthocyanin-rich fruits and vegetables have been well documented. Subsequently extensive research on anthocyanins has been carried out to better understand the behaviour of anthocyanins. Bioavailability is one aspect which has been frequently investigated but the studies have not studied factors affecting anthocyanin bioavailability. Knowledge of the mechanism of anthocyanin absorption is also lacking. A bioavailability study was conducted with human volunteers whose urine was analysed following consumption of strawberry and red grape juice. Since anthocyanins are

The total synthesis of cyanindin-3-glucoside (C3G) appropriate for ��C enrichment at C-1` and C-6` has been achieved for metabolic studies.

Abstract:

Anthocyanins, the class of flavonoid responsible for giving a red hue to many berries, have been associated with a decreased risk of cardiovascular disease. However, numerous intervention studies feeding anthocyanin-rich foods report limited (<1%) bioavailability of the parent anthocyanins in vivo. Due to the instability of anthocyanins at neutral pH, it is postulated that degradation products and metabolites of anthocyanins may be responsible for the perceived bioactive effects.

Anthocyanins are plant pigments offering a range of colours to fruits and flowers. Many properties of anthocyanins are influenced by the degree and type of side chain modifications. Though much is known about the biosynthesis of anthocyanins and the enzymes involved in side-chain decoration, there is limited understanding of the structural features of anthocyanin acyltransferases that determine their substrate preference. Anthocyanin acyltransferases belong to the BAHD family of enzymes and are involved in acylation. Through mutagenesis I showed that an arginine positioned close to motif-1 in

Anthocyanins were added to the diet at 0.03, 0.1 or 0.3% (w/w) for the animals' life time. Adenoma number and size were measured at the end of the experiment (week 16). Both interventions reduced adenoma number/burden in a dose-dependent fashion. A potential mechanism by which anthocyanins are thought to exert cancer chemoprevention is anti-oxidation. Anti-oxida

Abstract:

Anthocyanins are very important nutraceuticals not only because they protect plants against biotic and abiotic stresses (Winkel-Shirley, 2002) and they seem to be involved in plant yield (Frascaroli and Landi, 1998), but also because they exert antioxidant abilities able to protect human and animal health (Virgili and Marino, 2008). Maize is able to accumulate anthocyanin in different tissues (Escribano-Bailon et al., 2004; de Pascual-Teresa et al., 2002), so that it can be considered a functional food. On this basis the general aim of this PhD project was to develop maize genotypes with the u

Abstract:

Les paramètres thermodynamiques et les cinétiques d’interactions entre des polyphénols (des procyanidines et des anthocyanes) et des fractions pectiques ont été déterminés par des méthodes physico-chimiques en solution et sur support solide. Les expériences ont été réalisées avec les anthocyanes majoritaires de cassis ou des procyanidines de type B (extraites de pomme) avec différents degrés de polymérisation et des fractions pectiques issues de pectines de pomme présentant divers degrés de méthylation et différentes chaines latérales d’oses neutres.Les interactions entre les anthocyanes et le

Abstract:

Mestrado Vinifera EuroMaster - Instituto Superior de Agronomia<br>The treatment of wine with fining agents is a common practice in the wine industry which aims to achieve wine’s clarity and improves its stability along the time. The objective of this work was to examine the influence of various animal proteins used as fining agents on the anthocyanins’ profile. For this experiment, two Portuguese varieties, Touriga Nacional and Trincadeira have been used in which two different concentrations have been applied for each fining product. The fining agents are commercial fining products widely used
