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.
