TLDR
From the fruits of Sambucus canadensis four anthocyanin glycosides have been isolated by successive application of an ion-exchange resin, droplet-counter chromatography and gel filtration, determining the structure of the novel, major pigment, cyanidin 3-O-[6-O-(E-p-coumaroyl-2-O]-5-O-beta-D-glucopyranoside].About:

Anthocyanins – nature, occurrence and dietary burden
TL;DR: A review of the literature on the occurrence of anthocyanins in foods and their transformation during processing, including the formation of adducts and derived tannins, can be found in this paper.

Anthocyanins as natural food colours—selected aspects
P. Bridle,C.F. Timberlake +1 more
TL;DR: The anthocyanins have a long history as part of the human diet, these and other flavonoids, are receiving renewed attention for their positive health attributes as discussed by the authors, and the principal commercially available Anthocyanin food colorants, grape, elderberry, red cabbage and roselle, are considered and others mentioned Factors affecting the usage of extracts, in terms of colour hue and stability are discussed Chemical aspects of anthophyanin colour are summarised briefly and the advantages of acylation for color durability noted as a promising area for future development Special emphasis is placed

Colour and stability of pure anthocyanins influenced by pH including the alkaline region
TL;DR: In this article, a study on petanin color variation (intensity, λmax, e) over the pH range 1-9 during 60 days of storage, was conducted on petunidin 3-[6-O-(4-O-E-p-coumaroyl]-O-α-l-rhamnopyranosyl)-β-d-glucopyraniumide]-5-O-,β-γ-d−glucophyranoside (petanin) and cyanidin (cy3gl

Anthocyanins and other polyphenolics in American elderberry (Sambucus canadensis) and European elderberry (S. nigra) cultivars
Jungmin Lee,Chad E. Finn +1 more
TL;DR: Sufficient variability was seen among these genotypes to suggest that a successful breeding program could be carried out to improve levels of the various compounds evaluated in this study.

Improved spectral resolution in cosy 1H NMR spectra of proteins via double quantum filtering.
TL;DR: The elimination of the dispersive character of the diagonal peaks in phase-sensitive, double quantum-filtered COSY spectra allows identification of cross peaks lying immediately adjacent to the diagonal, which represents a significant improvement over the conventional COSy experiment.

An improved method for heteronuclear chemical shift correlation by two-dimensional NMR
Ad Bax,Gareth A. Morris +1 more
TL;DR: In this paper, the authors proposed to use phase cycling of the proton and carbon-13 transmitter pulses, similar to that recently introduced in homonuclear correlation experiments, allowing positive and negative f, frequencies to be distinguished.
Journal ArticleDOI
Food colorants: Anthocyanins
TL;DR: The natural colorant area can be subdivided into anthocyanins, betalains, chlorophylls, carotenoids, flavonoids, polyphenols, Monascus, hemes, quinones, biliproteins, safflower, turmeric, and miscellaneous.
