 "These compounds are localized in the outer layers of the seed coat, but are not epicuticular. They are deposited in the seed coat after seed coat dry weight accumulation has essentially stopped, but at the same time as embryo dry weight and neutral lipid are increasing."​ \\ "These compounds are localized in the outer layers of the seed coat, but are not epicuticular.

 The commercial extract or essential oil (hydrodistillation) from ambrette seeds is long been used in perfumery for its sweet, floral-musky,​ winelike odor. A mechanic separation of the water-soaked seed coats followed by alcoholic extraction and liquid-liquid extraction of the oleoresin obtained after removal of the alcoholic solvent with pentan or hexan, and removing fatty acids over a short column, led to an extract (0.24-0.29%) with sweet-smelling and lasting odor, almost free from fatty acids. Main components of this extract were decyl acetate (5.7%), dodecyl acetate (5.1%), farnesene (9.6%), (Z)-5-tetradecen-14-olide (1.3%), (Z)-5-tetradecenyl acetate (1.2%), (Z,​E)-2,​6-farnesyl acetate (3.8%), (E,​E)-2,​6-farnesyl acetate (50.4%), (Z)-7-hexadecen-16-olide (9.3%), (Z)-9-octadecen-18-olide (1.2%).\\ The commercial extract or essential oil (hydrodistillation) from ambrette seeds is long been used in perfumery for its sweet, floral-musky,​ winelike odor.
