Monoterpene hydrocarbons (P-cymene, myrcene, [gamma]-terpinene, limonene, terpinolene, and (Z)-[beta]-ocimene), oxygenated monoterpenes (carvacrol methyl ether, 2,5-dimethoxy-p-cymene, trans-chrysanthenyl acetate, cis-chrysanthenyl acetate, and ferulagone), aldehydes (like 2,3,6-trimethylbenzaldehyde, (E)-2-decenal, and octanal
), alkane derivatives (hexadecanoic acid), sesquiterpene hydrocarbons ([alpha]-humulene, 4,6-guaiadiene, and 7-epi-1,2-dehydrosesquicineole), and oxygenated sesquiterpenes (like cubenol, humuleneepoxide II, and spathulenol) were the major components of some Ferulago species.
The minor compounds, accounting for 0.01% to 8.5% of the total volatile compounds, included propanal, butanal, 3-methyl butanal, pentanal, heptanal, benzaldehyde, octanal
, nonanal, butane, carbon disulfide, 2-butene, n-pentane, hexane, heptane, octane, ethylacetate, 2-butanone, 2,3-butanedione, 3-hydroxy-2-butanone, 2-heptanone, 2,3-octanedione, dimethyl sulfide, ethanol, isopropyl alcohol, 1-pentanol, and 1,3,5-cycloheptatriene.
The researchers precisely determined the nature and concentrations of these compounds, and found heptanal, octanal
and nonanal, which are known as aldehydes in chemistry, to be emitted at higher levels by children with malaria.
Notable amounts of D-limonene, octanal
and nonanal were found in the odorous resins.
and only 4 (hexanal, octanal
, nonanal, and benzaldehyde) by Thomas .
The key aroma active compounds in vitamin A and D concentrates were: hexanal, Z-3hexen-1-ol, isoamyl acetate, octanal
, limonene, phellandrene, damascone, ionone, cyclocitral and irone.
Volatile aldehydes accounted for a substantial fraction of these samples (32.8%), the most abundant being furfural (15.2%), followed by hexanal, (E)-2-heptenal, benzaldehyde, octanal
, and heptanal.

However, 11 compounds out of 33 detectable compounds were found at both temperatures (e.g., n-nonane and octanal
