| | (+)-DIHYDROCARVONE Usage And Synthesis |
| Chemical Properties | p-Menth-8-en-2-one has an herbaceous, spearmint-like odor. | | Occurrence | Reported present in oregano oil, celery, spearmint oil, scotch spearmint oil, thymus, dill herb and seed and
caraway seed. | | Uses | The dual, herbal-minty quality of this compound will add an interesting twist to mint flavors as well as to celery, caraway, dill and herbal flavors, especially intended for cough drops and oral care products. At very low levels, it will add depth to tropical flavors like lychee, guava, passion fruit and rambutan. | | Uses | The N-functionalization of dihydrocarvone forms imine derivatives, which are synthons for preparing N-heterocycles. | | Definition | ChEBI: A dihydrocarvone resulting from reduction of the endocyclic cyclohexene double bond. | | Aroma threshold values | Detection: 820 ppb to 1.06 ppm | | Synthesis Reference(s) | Journal of the American Chemical Society, 89, p. 2794, 1967 DOI: 10.1021/ja00987a087
Tetrahedron Letters, 30, p. 6567, 1989 DOI: 10.1016/S0040-4039(01)89023-7 | | General Description | Natural occurence: Caraway seed, celery seed, dill, patchouli, spearmint, buchu and pepper | | Biochem/physiol Actions | Taste at 2-4ppm | | Safety Profile | Moderately toxic by
subcutaneous route. A skin irritant. When
heated to decomposition it emits acrid
smoke and irritating fumes. |
