Chemotypes :

Liatrix is the only species of the genus Liatris grown for perfumery. Other species exist such as Liatris savannensis and Liatris tugida among other 35 species.

Extraction process :

In the United States, Liatrix fields are perennial and grow by collecting and sowing the seeds of the plant. The seeds must be collected once the plant is dry, after a few weeks and must have a black and dry appearance.
For their use in perfumery, liatrix leaves are collected by hand and dried in the sun. Then, the most volatile molecules evaporate from the leaves and only the heavier molecules remain. This is why the smell of liatrix is very coumarin and hot.
The extraction with hexane gives a concrete after the plants are removed from the extractor and the solvent has evaporated. This first extract is pasty because it contains waxes. A treatment with alcohol is made to obtain the absolute by precipitating the waxes, which are insoluble in the alcohol, and by subjecting the concrete to a glazing process at 32 °F. After filtration of the opaque mixture, the alcohol is evaporated and the liatrix absolute is obtained.
