Phlobaphenes

from Wikipedia, the free encyclopedia
Phlobaphene are responsible for the red color in some maize varieties.

Phlobaphene (derived from the Greek phloios = inner bark and baphe = dye ) or tannin red are a group of secondary plant substances that belong to the group of tannins .

Chemically, they are very poorly defined. They arise from flavanols or from oligomeric proanthocyanidins , so their precursors are flavonoids . They form when drugs dry . Their color is often red, but goes as far as brown-black. They are high molecular weight polymers. Their formation is accelerated by oxidizing enzymes.

Phlobaphenes do not have an astringent effect .

They cause the red color of some herbal drugs, such as the ratanhiaroots , tormentil , cinnamon , clove or kola nut .

The CAS number 71663-19-9 was assigned to Phlobaphene .
