Reduction of selected betacyanins

, 2014
Betacyanins are conjugates of betalamic acid and glycosylated cyclo-DOPA which bring about the creation of a specific chromophoric system, the 1,7-diazaheptamethin chain. Betanin, a betacyanin pigment from red beet (Beta vulgaris L.), as well as its decarboxylated derivatives were subjected to reduction with the use of NaBH4.

A modifiedAmaranthus betacyanin test for cytokinin bioassay

Biologia Plantarum, 1975
A modified procedure for the extraction of betacyanin fromAmaranthus seedlings is described. Application of this modification increased the absorbance of cytokinin-treatedAmaranthus explants in most cases. The modifiedAmaranthus test is compared with the soybean callus test in the bioassay of kinetin, 6-benzylaminopurine, and 6(δ,δ-dimethylallyl ...
