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[edit]

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

See also[edit]

Isoorientin (or homoorientin) is the luteolin-6-C-glucoside.

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
