Biological Activities of Plant Pigments Betalains

Critical Reviews in Food Science and Nutrition, 2014
Betalains are a family of natural pigments present in most plants of the order Caryophyllales. They provide colors ranging from yellow to violet to structures that in other plants are colored by anthocyanins. These include not only edible fruits and roots but also flowers, stems, and bracts.

Beeturia and the biological fate of beetroot pigments

Pharmacogenetics, 1993
Beeturia, the passage of pink or red urine after the ingestion of beetroot, is said to occur in 10-14% of the population, and is more common in iron deficiency and malabsorption. A specific HPLC assay for betacyanins, the red beetroot pigments, in biological fluids was developed to study the prevalence of this apparent polymorphism in humans, and to ...

Biological activities of oligoketide pigments of Monascus purpureus

Food Additives & Contaminants, 1999
Rubropunctatin (1), monascorubrin (2), monascin (3) and ankaflavin (4) were purified from the mycelium of Monascus purpureus by flash chromatography on silica gel or reversed phase. Their embryotoxicity towards chicken embryos decreased in the order 2 > 1 > 3 > 4.

In vivoautofluorescence in the biological windows: the role of pigmentation

Journal of Biophotonics, 2015
Small animal deep-tissue fluorescence imaging in the second Biological Window (II-BW, 1000-1350 nm) is limited by the presence of undesirable infrared-excited, infrared-emitted (900-1700 nm) autofluorescence whose origin, spectral properties and dependence on strains is still unknown.
