Differential partitioning of betacyanins and betaxanthins employing aqueous two phase extraction

Journal of Food Engineering, 2015
Yellow betaxanthins and red purple betacyanins are genetically and structurally closely related pigments, hence making their separation from each other difficult and tedious. Fractionation of betalains into betacyanin and betaxanthin could be achieved by employing aqueous two-phase extraction (ATPE).

BpCYP76AD15 is involved in betaxanthin biosynthesis in bougainvillea callus

BpCYP76AD15 is involved in betaxanthin biosynthesis in bougainvillea callus
Bougainvillea (Bougainvillea peruviana) is a climbing tropical ornamental tree belonging to Nyctaginaceae. Pigments that are conferring colorful bracts in bougainvillea are betalains, and that conferring yellow color are betaxanthins. In general, for red-to-purple betacyanin biosynthesis, α clade CYP76AD that has tyrosine hydroxylase and DOPA oxygenase

Enhancing extraction of betalains from beetroot (Beta vulgaris L.) using deep eutectic solvents: optimization, bioaccessibility and stability

Food Production, Processing and Nutrition
Deep eutectic solvents (DESs) are the next generation of green solvents that are considered for their stability and biocompatibility. This study used 10 different DESs synthesized from choline chloride, alcohols, organic acids and sugars.

Amino Acid Betaxanthins: Absorption, Fluorescence, And Stability. [PDF]

J Nat Prod
Betaxanthins are natural pigments responsible for the vivid yellow coloration and intrinsic fluorescence of flowering succulent plants within the order Caryophyllales. Though less extensively studied than other plant pigments classes, betaxanthins hold potential for application as safe food dyes, solar cell absorbers, antioxidants, and genetically ...

Dynamics of changes in the content of betalain pigments in red beet roots during the growing season and storage

Овощи России, 2023
Purpose. Betalains, plant pigments of red beet roots, exhibit antioxidant activity and reduce the risks of many pathological conditions. However, the widespread introduction of betalains is hampered by insufficient knowledge of their transformations ...

Identification of <i>CqCYP76AD5v1</i>, a gene involved in betaxanthin biosynthesis in <i>Chenopodium quinoa</i>, and its product, betaxanthin, which inhibits amyloid-β aggregation. [PDF]

Plant Biotechnol (Tokyo)
Betalain pigments, primarily produced by the order Caryophyllales, are categorized into betacyanins (red/purple) and betaxanthins (yellow/orange). While the biosynthetic pathways of these pigments are well-studied, the genes responsible for betaxanthin biosynthesis in quinoa were previously unknown.
