L(-)-Carvone Usage And Synthesis
DescriptionL-(-)-Carvone is the principal odor component of spearmint. It is with a refreshingly cool, minty odor and taste. It is used as flavor ingredient in a variety of foods and beverages, as well as in toothpaste and mouthwash. It is used as a fragrance in personal care products. It is intended for use in the manufacture of an area repellent for mosquitoes and biting flies. L-(-)-carvone is also used in agriculture as a sprout inhibitor of potatoes.

Chemical Propertiesclear colorless to pale yellow liquid
Chemical PropertiesCaravone occurs in different forms. l-Carvone exhibits odor of spearmint, while d-carvone exhibits odor reminiscent of caraway.
OccurrenceR-Carvone is the main substance in spearmint oil, also present in toothpastes; it is the cause of delayed-type allergy resulting in cheilitis, but Hansson et al. also described a case of angioedema of the lips appearing within minutes after contact with toothpaste, with an open test resulting in an immediate and strong reaction to carvone.
DefinitionChEBI: A carvone having (R) configuration.
Aroma threshold valuesDetection: d-Carvone: 6.7 to 820 ppb; l-carvone: 2.7 to 600 ppb
Safety ProfilePoison by intravenous route. Moderately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes.
Chemical SynthesisCarvone occurs in the dextro, levo and racemic form; l-carvone can be isolated from the essential oil of spearmint or is commercially synthesized from d-limonene; d-carvone is usually prepared by fractional distillation of oil of caraway, also from dillseed and dillweed oils, but this type differs in odor and flavors.
