It consists of cyclohex-2-enone with isopropenyl and methyl substituents at positions 2 and 5, respectively. It mainly plays a role of allergen but since it’s a member of the carvone family, it is a botanical antifungal agent.
It exhibits several biological properties such as antimicrobial, anticancer, anti-inflammatory, antidiabetic, neurological, and many other pharmacological effects through its varied effects on the subcellular, cellular, and molecular levels.
Uses of Carvones
D-carvone is used in veterinary medicines to treat flatulence and disturbances of the stomach and gut in farmed animals, as well as to facilitate breathing in newborn animals.
Aromatherapy oils, personal care products, air fresheners, and air fresheners contain natural (R)-carvone for flavoring and aroma.
Carvone manufacturers have a huge demand in the western countries’ agricultural sector. For instance, the Dutch market sells S-(+)-Carvone under the name Talent to prevent the premature sprouting of potatoes during storage.
Due to its availability in both enantiomerically pure forms at a reasonable price, carvone is an attractive starting material for the asymmetric total synthesis of natural products. For instance, (S)-(+)-carvone was used to begin a 1998 terpenoid quassin.
Stereoisomerism and odor application
You will find two mirror images of Carvone forms or enantiomers i.e. R-(−)-carvone, or L-carvone, which has a sweet minty smell. This smell is similar to spearmint leaves. On the other hand, the mirror image, S-(+)-carvone, or D-carvone, has a spicy aroma. Due to the difference in perception of smell between the two enantiomers, one enantiomer must stimulate olfactory receptors more strongly than the other. Therefore many foods and fragrance industries tie up with carvones manufacturers to use the carvones either as a flavoring agent or to enhance the odor of their products.
