+The most potent odorants (highest FD factor, 6-10) of a Chinese conrmint 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.\\

+The essential oil of the leaves and twigs of nana mint (Mentha spicata L. ssp.spicata, syn.Mentha viridis L. var.nanah) is characterized by higher amounts of (-)-limonene (14-31%), 1,8-cineole (0.8-6.7%; cineole:limonene <0.5), (-)-carvone (53-65%), minor amounts of menthol (<0.5%), and the absence of isopulegole (M.arvensis!) and menthofuran (M.piperita!).\\

+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." \\
