How is Orris oil (CAS: 8002-73-1) typically synthesized?

Orris oil (CAS: 8002-73-1) is typically synthesized through steam distillation of the roots of Iris florentina. The process involves heating the roots in water to release the volatile compounds into steam, which is then condensed and collected. The yield is around 0.1% to 0.2% of the dry root weight. The process is selective and efficient, producing a high-quality essential oil.
