Betacyanins of some chenopodiaceae

Phytochemistry, 1971
Abstract Four species of the Chenopodiaceae have been investigated for their betacyanin content. From the leaves of Suaeda fruticosa a new acylated pigment has been isolated and identified as citryl-celosianin.

Heat stability of betacyanins

Zeitschrift f�r Lebensmittel-Untersuchung und -Forschung, 1983
The heat decomposition of betacyanins takes place at pH 2.2–4.0 according to the first-order kinetics; at pH value 5.0 and above the complete decomposition of betacyanins can be better described using a rational exponent-order kinetics. The destruction rate of betacyanins strongly depends on the temperature.

Betacyanins from bracts of Bougainvillea glabra

Phytochemistry, 1994
Betacyanins from the bracts of Bougainvillea glabra were isolated and characterized by a combination of spectroscopic techniques (DAD-HPLC, NMR, LC-MS, GC-MS, electrospray MS, tandem MS) as gomphrenin I (betanidin 6-O-beta-glucoside) and various derivatives of bougainvillein-v (betanidin 6-O-beta-sophoroside), i.e.

Betacyanins from vine cactus Hylocereus polyrhizus

Phytochemistry, 2001
The presence of betacyanin pigments and their isoforms has been detected in the fruit of Hylocereus polyrhizus, a vine cactus native to South America. Along with the known betanin and phyllocactin (6'-O-malonylbetanin), a new betacyanin was structurally elucidated as betanidin 5-O-[6'-O-(3"-hydroxy-3"-methyl-glutaryl)-beta-D-glucopyranoside] (proposed ...

Intramolecular stabilization of acylated betacyanins

Phytochemistry, 1998
Abstract Racemization and stability of the betacyanins, betanin (betanidin 5-O-glucoside) and amaranthin(betanidin 5-O-glucuronosylglucoside), under acidic conditions were compared with those of the corresponding feruloyl derivatives, lampranthin II and celosianin II.

Betacyanins of the family cactaceae

Phytochemistry, 1969
Abstract Thirty-four species of the family Cactaceae have been investigated for their betacyanin content. All the species examined contain betanin and many of them also phyllocactin. Betanidin and some new betacyanins have a more limited occurrence.

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.

Characterisation, stability and application of betacyanins and microencapsulated betacyanins to sunscreen formulations

2021
The thesis is about extraction of betacyanins from red dragon fruit and red spinach, and application of maltodextrin-encapsulated betacyanins from red dragon fruit in sunscreen formulations.

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.
