-The most potent odorants (highest FD factor, 6-10) of a Chinese cornmint oil were isomenthone (11.2%, minty dirty leafy), menthone (22.1%, minty clean cooling), 2,5-diethyltetrahydrofuran (0.03%, pungent solvent ether), (E)-ß-damascenone (trace, fruity woody berry), 1,8-cineole (0.4%, cooling eucalyptus), menthol (34.9%, cooling minty clean), pulegone (1.5%, heavy minty dirty), ß-ionone (heavy woody fruity), eugenol (0.04%, spicy clove sweet), linalool (0.1%, floral sweet creamy), (E,Z)-2,6-nonadienal (leafy floral cucumber), carvone (0.2%, spearmint fruity herbal), guaiacol (sweet smoky phenolic), 4-vinylguaiacol (smoky woody sweet), and five unknown compounds.\\

 Spearmint essential oil is dominated by carvone (37.7%), menthol (16.1%), limonene (15.0%), and menthone (9.7%), with smaller abundances of isomenthone (4.4%), neomenthol (2.4%), menthyl acetate (1.4%) and cis-dihydrocarvone (1.1%). Menthofuran was not found.\\ Spearmint essential oil is dominated by carvone (37.7%), menthol (16.1%), limonene (15.0%), and menthone (9.7%), with smaller abundances of isomenthone (4.4%), neomenthol (2.4%), menthyl acetate (1.4%) and cis-dihydrocarvone (1.1%).

 +"...(-)-carvone was the most potent odorant in all three spearmint oils. In Native spearmint oil, other potent odorants included eugenol (clove), ethyl-2-methylbutyrate (fruity), β-damascenone (applesauce), (3E,5Z)-1,3,5-undecatriene (tape), and methional (cooked potato). In Scotch spearmint oil, other potent odorants were eugenol, (3E,5Z)-1,3,5-undecatriene, β-damascenone, isoeugenol, and an unknown minty odorant (RIWAX= 1719). In Macho mint oil, additional potent odorants included eugenol, (3E,5Z)-1,3,5-undecatriene, ethyl-2-methylbutyrate, and β-damascenone. Important odorants which remain unknown include two minty odorants (RIWAX= 1425 and 1719), a bread-like odorant (RIWAX= 1434), and an insect repellent-like odorant (RIWAX= 2366)... some compounds, such as dimethyl trisulfide and 3-methyl-2-butene-1-thiol, had high FD factors yet were not detectable by GC-MS. This can be attributed to the low odor thresholds of these compounds. The threshold for dimethyl trisulfide is 0.01 parts per billion, and the threshold for 3-methyl-2-butene-1-thiol is 1.2 parts per trillion (Buttery et. al., 1976; Fritsch and Schieberle, 2005). These trace potent odorants are typically overlooked due to their low concentrations, yet are significant to the overall flavor of spearmint oils." \\

 Aroma extract dilution analysis (AEDA) of spearmint oils showed (R)-(−)-carvone as the most potent odorant. Additional predominant odorants included eugenol, ethyl (S)-(+)-2-methylbutanoate, (E)-β-damascenone, and (3E,5Z)-1,3,5-undecatriene. "Among the compounds quantitated, those with the highest OAVs were (R)-(−)-carvone, 1,8-cineole, (E,Z)-2,6-nonadienal, (E)-β-damascenone, and (3E,5Z)-1,3,5-undecatriene." \\ Aroma extract dilution analysis (AEDA) of spearmint oils showed (R)-(−)-carvone as the most potent odorant.

 +"While L-carvone represents about 60-75% of spearmint oil, it doesn't provide the distinct odor and flavor of the natural spearmint oil, which in addition to L-carvone contains carveol (0.4-0.7%), carvyl acetate (1-2%), dihydrocarveol (0.1-0.2%), and dihydrocarvyl acetate (0.3-0.4%) among many other components... L-carvyl acetate and L-dihydrocarvyl acetate, are essential for creating the distinct spearmint flavor." \\
