Caraway was used for medicinal purposes by the ancient Romans, but carvone was probably not isolated as a pure compound until Franz Varrentrapp (1815–1877) obtained it in 1849. It was originally called carvol by Schweizer. Goldschmidt and Zürrer identified it as a ketone related to limonene, and the … See more Carvone is a member of a family of chemicals called terpenoids. Carvone is found naturally in many essential oils, but is most abundant in the oils from seeds of caraway (Carum carvi), spearmint (Mentha spicata), and See more Carvone forms two mirror image forms or enantiomers: R-(−)-carvone, or L-carvone, has a sweetish minty smell, like spearmint leaves. Its mirror … See more The dextro-form, S-(+)-carvone is obtained practically pure by the fractional distillation of caraway oil. The levo-form obtained from the oils containing it usually requires additional treatment to produce high purity R-(−)-carvone. This can be achieved by the … See more In the body, in vivo studies indicate that both enantiomers of carvone are mainly metabolized into dihydrocarvonic acid, carvonic acid and uroterpenolone. (–)-Carveol is also formed as a minor product via reduction by NADPH. (+)-Carvone is likewise converted … See more Both carvones are used in the food and flavor industry. R-(−)-Carvone is also used for air freshening products and, like many essential oils, … See more 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 … See more Reduction There are three double bonds in carvone capable of reduction; the product of reduction depends on the reagents and conditions used. … See more WebSep 14, 2024 · Carvone and carvotanacetone are monoterpene ketones synthesized by the methylerythritol phosphate pathway in plastids via geranyl-pyrophosphate through an intermediate like limonene or β-pinene in some microorganisms and plants.
