Formula: C 10 H 14 O 2; Molecular weight: 166.2170; IUPAC Standard InChI: L-Carvone is predicted to have a comparable level of repeated dose toxicity to D-Carvone, so using a read-across approach, a NOAEL of 375 mg/kg bw/day is predicted for L-carvone. In addition, published toxicokinetic data demonstrates that L- and D-Carvone have no differences in metabolism, which further supports the read-across application (Engel, 2001). The chirality of carvone is directly translated into a discrepancy in smell because several olfactory receptors in your nose are chiral and will register certain enantiomers more strongly than others. Thus, (R) carvone smells like spearmint and (S) carvone smells like caraway.

Occurrence. S - (+)-Carvone is the principal constituent (60–70%) of the oil from caraway seeds ( Carum carvi ), which is produced on a scale of about 10 tonnes per year. It also occurs to the extent of about 40–60% in dill seed oil (from Anethum graveolens ), and also in mandarin orange peel oil.
