Orris odors

The irones (167,168,169), which constitute slightly more than 75% of the volatiles, are primarily responsible for the fine odor of the natural material. For this reason and because of the high cost of orris absolute, synthetic versions of the irones have been commercialized. Of the possible irone stmctures, the y-isomer (168) possesses the best fragrance properties.

Vitivert, or Kus-hus.—The fleshy part of a specter of dry grass from India, It has an aromatic odor, and is used in the same manner as orris root. The tincture or extract of vitivert is made by digesting one pound of the dried root in a quart of alcohol for two weeks, and filtering.
