Chemical structures of (−)-cis-γ-irone (top) and (−)-cis-α-irone
Irones are a group of methylionone odorants used in perfumery, derived from iris oil, [1] e.g. orris root. The most commercially important of these are:

- (−)-cis-γ-irone, and
- (−)-cis-α-irone
Irones form through slow oxidation of triterpenoids in dried rhizomes of the iris species, Iris pallida . Irones typically have a sweet floral, iris, woody, ionone, odor.
