Irones are a group of methylionone odorants used in perfumery, derived from iris oil, 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.

The odorous constituent of oil of Orris is a liquid ketone named Irone, to which the violet-like odour is due (though it is not absolutely identical with oil of Violets obtained from the natural flower), and it is the presence of this principle in the rhizome that has long led to the employment of powdered Orris root in the preparation of Violet powders, which owe very little of their scent to the real Violet perfume.
It was first isolated by the eminent chemist Tiemann and formed the basis of his researches on artificial Violet perfume, and in 1893 he succeeded in preparing an allied body, which was termed Ionone and which had an odour even more like that of Violets than had Irone, and is now largely manufactured for the perfumery trade in making toilet waters and handkerchief extracts.
