In an expedition for green-energy generation and to lower the cost per watt of solar energy, environmentally friendly biotic colorants were separated from Tectona grandis seeds. The prime colorant in extract is pelargonidin which sensitizes titanium dioxide (TiO2)-based photo anodes. pelargonidin-sensitized TiO2 nanomaterials endured structural, photosensitive, spectral current-voltage interpre...

Purple carrots (Daucus carota ssp. sativus var. atrorubens Alef.) accumulate large amounts of cyanidin-based anthocyanins in their taproots. Cyanidin can be glycosylated with galactose, xylose, and glucose in sequence by glycosyltransferases resulting in cyanidin 3-xylosyl (glucosyl) galactosides in purple carrots. The first step in the glycosylation of cyanidin is catalysis by UDP-galactose: c...

Abstract A comparative metabolomic analysis was performed using purple potato tubers and derived red mutant to investigate the regulation of anthocyanin biosynthesis. The metabolome revealed 19 key differential metabolites including 10 flavonoids 4 nucleotides. As a metabolite, pelargonidin responsible for mutant, other had correlation with it. To further analyse regulatory mechanism metabolite...

The interaction of the cyanidin, pelargonidin, catechin, myrecetin and kaempferol with casein and gelatin, as proline rich proteins (PRPs), was studied. The binding constants calculated for both flavonoid-casein and flavonoid-gelatin were fairly large (10 (5) -10 (7) M (-1) ) indicating strong interaction. Due to higher proline content in gelatin, the binding constants of flavonoid-gelatin (2.5...

Qin C., Li Y., Niu W., Ding Y., Zhang R., Shang X. (2010): Analysis and characterisation of anthocyanins in mulberry fruit. Czech J. Food Sci., 28: 117–126. The fruit of mulberry (Morus alba L., Moraceae) has been used as medicinal food in China for a long history. The pigment from the fruit extract is a kind of natural colourant for food processing and has potential medical and commercial valu...

Flavonoids play an important role in the pigmentation of flowers; in addition, they protect petals and other flower parts from UV irradiation and oxidative stress. Nudicaulins, flavonoid-derived indole alkaloids, along with pelargonidin, kaempferol, and gossypetin glycosides, are responsible for the color of white, red, orange, and yellow petals of different Papaver nudicaule cultivars. The col...
