    • 1934, Drug and Cosmetic Industry, Volume 35, Harcourt Brace Jovanovich, page 256:
      As is well known, Irone is the principal odoriferous constituent of Orris Butter, the essential oil obtained from Orris Root by steam distillation.
    • 1951 [D. Van Nostrand], Frank C. Whitmore, Organic Chemistry, Volume One: Part I: Aliphatic Compounds, Part II: Alicyclic Compounds, 2nd Edition, 2012, Dover republication, page 565,
      The previously accepted cycloheptene structure for the irones has been shown recently to be wrong.
    • 1999, Karl Swift, “The Total Synthesis of Synthetically Interesting Perfumery Natural Products”, in K. A. Swift, editor, Current Topics in Flavours and Fragrances: Towards a New Millennium of Discovery, Kluwer Academic Publishers, page 19:
      The constituents of Orris (Iris) oil that we shall be concerning ourselves with in this chapter are the irones (22-24). Orris oil comes from the steam distillation of the rhizomes of Iris pallida (which contains the major irone components; (-)-trans-α-irone, (+)-cis-γ-irone, (+)-cis-α-irone, (+)-β-irone, and (+)-trans-γ-irone) or Iris germanica. Both species of iris contain the same irones except that the irones in Iris germanica are the optical antipodes of those found in Iris pallida [27].
