Acylated betacyanins from Drosanthemum floribundum

Phytochemistry, 1973
Abstract Four new acylated betacyanins have been isolated from flowers of Drosanthemum floribundum (Haw.) Schwant. These pigments were characterized as hydroxycinnamoyl derivatives of betanin and isobetanin.

The betacyanins and their distribution

Phytochemistry, 1963
Abstract Thirty-eight species, including thirteen previously uninvestigated genera, in ten families usually grouped in the Centrospermae were surveyed by electrophoresis and chromatography for the presence of betacyanin and anthocyanin pigments. Betacyanins were observed in all thirty-eight species but no anthocyanins were detected.

Formation and occurrence of dopamine-derived betacyanins

Phytochemistry, 2001
In light of the fact that the main betaxanthin (miraxanthin V) and the major betacyanin (2-descarboxy-betanidin) in hairy root cultures of yellow beet (Beta vulgaris L.) are both dopamine-derived, the occurrence of similar structures for the minor betacyanins was also suggested.

Betacyanins from Lampranthus sp. (aizoaceae)

Phytochemistry, 1969
Abstract Isolation and characterization of four betacyanins from flowers of Lampranthus sp. is reported. These pigments have been shown to be hydroxycinnamoyl derivatives of betanin and isobetanin.

The decolorization of betacyanin by polyamines

Phytochemistry, 1985
Abstract The pigment betacyanin, the efflux of which has been used as a measure of membrane integrity in red beet discs, has now been shown to react with di- and polyamines with consequent decolorization.

Betacyanins from flowers of Gomphrena globosa

Phytochemistry, 1992
Abstract The betacyanins gomphrenin I (betanidin 6- O -β-glucoside) and its acylated forms gomphrenin II (betanidin 6- O -[6′- O -( E -4-coumaroyl)-β-glucoside]) and gomphrenin III (betanidin 6- O -[6′- O - E -feruloyl-β-glucoside]) were isolated from flowers of Gomphrena globosa and their structures elucidated by NMR spectroscopy and ion spray ...

Fruit Flesh Betacyanin Pigments in Hylocereus Cacti

Journal of Agricultural and Food Chemistry, 2002
Determination of profiles and total contents of betacyanins in cactus fruits of Hylocereus species using chromatographic and spectrophotometric method is described. The investigated species were H. polyrhizus, H. purpusii, H. costaricensis, H. sp. 487 (all red-flesh species and hybrids made among them), and the white- or red-flesh species H.

Betacyanins from fruits of Basella rubra

Phytochemistry, 1993
Abstract Ion spray mass spectrometry and tandem mass spectrometry of the fresh juice from Basella rubra fruits revealed the presence of betanidin monoglucoside as the major betacyanin and its 4-coumaroyl and feruloyl derivatives as minor components.

Chlorination of Betacyanins in Several Hypochlorous Acid Systems

Journal of Agricultural and Food Chemistry, 2016
This study presents a comparative evaluation of chlorination of betanin, betanidin, and neobetanin exposed to sodium hypochlorite and myeloperoxidase (MPO)/H2O2/Cl(-) systems. For betanin/betanidin, the chlorination takes place at the aglycone unit, but for neobetanin, no chlorinated products in the reaction mixtures can be detected.
