 "We also had in our hands all ten pure stereoisomers of irones. Only (-)-cis-α-irone (2S,6R) and (-)-trans-γ-irone (2S,6S) were found to possess the delicate and characteristic scent of orris butter, though the other irone samples were also described to smell pleasant of violet and woody notes." \\ "We also had in our hands all ten pure stereoisomers of irones.

 +"Orris butter is usually marketed in two grades: '8% irone' and '15% irone.' Considering that raw butter 
 +comes out of the still with 18-20% irone, irone calibration and standardization is achieved through the addition of natural myristic acid, a component of orris and by-product of absolute manufacturing." \\

 Orris root oil or "orris butter", produced by steam distillation of the grounded and carefully dried rhizomes, has a buttery nature because of various amounts of methyl and ethyl myristate. The typical odor of the oil (violet, floral, woody) is attributed to the irones, which are structurally related to the ionones. (of violet oil). Main constituents are (+)-cis-α-irone (39%), (-)-trans-α-irone (16%), (+)-β-irone (2%), (+)-cis-γ-irone (43%), with trace amounts of (+)-trans-γ-irone. \\ Orris root oil or "orris butter", produced by steam distillation of the grounded and carefully dried rhizomes, has a buttery nature because of various amounts of methyl and ethyl myristate.
