Orrisroot

the rootstock of several species of iris, which contains an essential oil with the fragrance of violet. Orrisroot is used as an aromatic agent. The oil of the species Iris germanica, I.florentina, and I. pallida is used commercially. The yield of oil constitutes 0.1–0.2 percent of the weight of raw rootstock.

The violet fragrance is due to the ketone irone, which constitutes approximately 12–15 percent of the oil.
