Treff et al. in 1929 disclosed the presence of five constituents in the hydrodistillation product from the absolute of carnation concrete: Eugenol (30%), 2-phenylethanol (7%), benzyl benzoate (40%), and methyl salicylate (1%). Derbesy et al. in 1980 found aliphatic acids C12-C20, citronellol, benzyl benzoate, hexyl benzoate, (Z)-3-hexenyl benzoate and eugenol. \\ | Treff et al. in 1929 disclosed the presence of five constituents in the hydrodistillation product from the absolute of carnation concrete: Eugenol (30%), 2-phenylethanol (7%), benzyl benzoate (40%), and methyl salicylate (1%).

An oil hydrodistilled from a commercial Egyptian hexane concrete contained mainly hydrocarbons C10-C29 (27%), alcohols (29%, C6-C10, linalool, geraniol, nerol, α-terpineol, (Z)-3-hexenol, benzyl alcohol, 2-phenylethanol), and esters like benzyl benzoate (11.8%), benzyl salicylate (1.5%), (Z)-3-hexenyl benzoate (1.1%), and methyl linoleate. Ethers and phenols included eugenol (20.8%) and methyl eugenol, benzylethylether, dibenzylether, (Z)-3-hexenyl benzylether, o- and p-cresol, and 2-methoxyphenol. Aldehydes C6-C10 were only present in minor amounts (1%) but had a great impact on the odour of the top note of the oil. Other oxygenated compounds with special odour impact were vanillin, benzaldehyde (0.9%), jasmone (0.4%), methyl jasmonate (0.01%), (Z)-3-hexenyl (E)-2-hexenoate, and (Z)-3-hexenyl (Z)-3-hexenoate. \\ | An oil hydrodistilled from a commercial Egyptian hexane concrete contained mainly hydrocarbons C10-C29 (27%), alcohols (29%, C6-C10, linalool, geraniol, nerol, α-terpineol, (Z)-3-hexenol, benzyl alcohol, 2-phenylethanol), and esters like benzyl benzoate (11.8%), benzyl salicylate (1.5%), (Z)-3-hexenyl benzoate (1.1%), and methyl linoleate.

An absolute (21.1% yiled from the concrete) contained mainly hydrocarbons (20%), a smaller amount of eugenol (3.6%). Contrary to the steam-distilled product, most constituents eluted (GC/MS) after eugenol. \\ | An absolute (21.1% yield from the concrete) contained mainly hydrocarbons (20%), a smaller amount of eugenol (3.6%).
