Orientin is a flavone, a chemical flavonoid-like compound. It is the 8-C glucoside of luteolin.

Natural occurrences[edit]

Orientin is found in Adonis vernalis, in Anadenanthera colubrina and Anadenanthera peregrina, and in the Phyllostachys nigra bamboo leaves[1]

In food

Orientin is also reported in the passion flower,[2] the Açaí palm, buckwheat sprouts,[3] and in millets.[4]

Identification in Natural Plants[edit]

The identification of orientin has been reported widely. Its identification using mass spectrometry is established [5]
