Betacyanins from bougainvillea

Phytochemistry, 1970
Abstract The isolation of seven new betacyanins from purple bracts of Bougainvillea “Mrs. Butt” is described. Two of these pigments, bougainvillein-r-I and isobougainvillein-r-I, have been shown to be 5- O -β-sophorosides of betanidin and isobetanidin, respectively, the remaining five being hydroxycinnamoyl derivatives of bougainvillein-r-I and ...

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.
