Red beetroot (Beta vulgaris L.) is a great source of betalains. The main betalains are the betacyanins, responsible for the purple color, and betaxanthins, which present a brownish color. These pigments can present antioxidant activity and are very unstable under certain conditions, such as temperature, extreme ranges of pH, and exposure to light.

Betalains in practical medicine
Pacific Medical Journal, 2023Betalains are plant pigments synthesized in the cells of Caryophyllales (red beets, opuntia, etc.). They are involved in the inactivation of reactive oxygen species and free radicals. The paper summarizes the data on the physical-chemical and pharmacological properties of betalains.

Plant betalains: Chemistry and biochemistry
Phytochemistry, 2015Betalains are vacuolar pigments composed of a nitrogenous core structure, betalamic acid [4-(2-oxoethylidene)-1,2,3,4-tetrahydropyridine-2,6-dicarboxylic acid]. Betalamic acid condenses with imino compounds (cyclo-l-3,4-dihydroxy-phenylalanine/its glucosyl derivatives), or amino acids/derivatives to form variety of betacyanins (violet) and betaxanthins

Primitively the term bioavailability was used in materia medica in order to describe the rate and extent of action of a drug. Many definitions of bioavailability were recommended, but the more accepted one is the fractional part of any ingested compound that enters the systemic circulation and the particular sites where this compound maintains its ...

Ecology gradually affects the biochemical composition of plant which is progressively influenced by conservationism. This observation is extensively supported when Caryophyllales is examined for its phytochemical characterization. So, anthocyanins are replaced by betalain in various vegetative parts mainly in flowers and fruits.

Stabilization of betalains: A review
Food Chemistry, 2016Betalains are vacuolar pigments composed of a nitrogenous core structure, betalamic acid [4-(2-oxoethylidene)-1,2,3,4-tetrahydropyridine-2,6-dicarboxylic acid]. This compound consists of a chromophore substructure 1,7-diazaheptamethin. Betalamic acid condenses with imino compounds (cyclo-DOPA or its glucosyl derivatives), or amines and/or their ...

Betalains are frequently present in composite mixtures. They quickly decompose in the separation stages and refining that makes separation of higher amounts of pigments difficult. Identification and structural elucidation of betalain molecules comprise of comparison of electrophoretic, chromatographic, and spectroscopic properties and involve direct ...

Chemical and Antioxidant Properties of Betalains
Journal of Agricultural and Food Chemistry, 2017Betalains are vacuolar pigments composed of a nitrogenous core structure, betalamic acid. Betalamic acid condenses with imino compounds (cyclo-DOPA/its glucosyl derivates) or amino acids/derivates to form violet betacyanins and yellow betaxanthins. These pigments have gained the curiosity of scientific researchers in recent decades.
