Recent advances in the development of smart, active, and bioactive biodegradable biopolymer-based films containing betalains [PDF]
Food Chemistry, 2022 Betalains are natural nitrogenous water-soluble pigments found in species belonging to the Caryophyllales order and in mushrooms. Betalains can be considered multifunctional molecules due to their diverse bioactivities such as antioxidant, antimicrobial,

Urinary pharmacokinetics of betalains following consumption of red beet juice in healthy humans
Pharmacological Research, 2005 The aim of the present pilot study was to characterise the renal elimination of betalains after consumption of red beet juice (RBJ). Six healthy, non-smoking female volunteers were given a single oral dose of either 500 mL of a commercial RBJ containing ...

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.

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 occur only in few plant families of order Caryophyllales where they found vital constituents in edible parts of plants usually in leaves, flowers, and stems. They also occur in some fungi of higher order like in the fly agaric (A. muscaria) and some genera of Basidiomycetes. Red beetroots (B.

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 ...

Betalains from Christmas cactus
Phytochemistry, 2000The presence of 14 betalain pigments have been detected by their characteristic spectral properties in flower petals of Christmas cactus (Schlumbergera x buckleyi). Along with the known vulgaxanthin I, betalamic acid, betanin and phyllocactin (6'-O-malonylbetanin), the structure of a new phyllocactin-derived betacyanin was elucidated by various ...

Anthocyanins occur widely in plants, being responsible for their blue, purple, violet, magenta, red and orange coloration; while betalains, consisting of red-violet betacyanins and yellow-orange betaxanthins, occur exclusively in families of the order Caryophyllales. The occurrence of these two classes of pigments is mutually exclusive. Their stability
