General description

trans-β-Apo-8′-carotenal is a linear aldehydic carotenoid. It is naturally found in oranges, spinach, grass, tangerines and marigolds and thus, it is directly absorbed from the diet.

Application

trans-β-Apo-8′-carotenal has been used as an internal standard during vitamin E analysis.

Biochem/physiol Actions

trans-β-Apo-8′-carotenal is commercially available as a food colorant.
Natural carotenoid that is formed from β-carotene in vivo and is an inducer of cytochrome P450 1A (CYP1A) in rats and in Ah-receptor-responsive mice.
