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.

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.

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 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.

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.

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.

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 are plant-based dyes with potential as histological stains

Biotechnic & Histochemistry, 2022
Interest is increasing in certain parts of the world in replacing synthetic dyes with dyes from natural sources, particularly from plants. Although textile dyers have used various groups of natural dyes, microscopists generally have restricted their use to anthocyanins.

Identification and Distribution of Simple and Acylated Betacyanins in the Amaranthaceae

Journal of Agricultural and Food Chemistry, 2001
Red-colored plants in the family Amaranthaceae are recognized as a rich source of diverse and unique betacyanins. The distribution of betacyanins in 37 species of 8 genera in the Amaranthaceae was investigated. A total of 16 kinds of betacyanins were isolated and characterized by HPLC, spectral analyses, and MS. They consisted of 6 simple (nonacylated)
