 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%).

 +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." \\ Aroma extract dilution analysis (AEDA) of spearmint oils showed (R)-(−)-carvone as the most potent odorant.

-{{:mantha_spicata.jpg?500}} \\+Investigating its pharmacological effects in the guinea pig ileum, "The effect of (−)-carvone was compared with that of the classical calcium channel blocker (CCB) verapamil... (−)-carvone reduced the contraction induced by high K+ and was almost 100 times more potent than verapamil. Thus, (−)-carvone showed a typical and potent CCB-like action. Many effects described for both (−)-carvone and spearmint oil can be explained as a CCB-like mode of action." \\
