     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].
