Pulegone

C10H16O (152.12010859999998)

A p-menthane monoterpenoid that is cyclohexan-1-one substituted by a methyl group at position 5 and a propan-2-ylidene group at position 2. Occurs in oils of Mentha subspecies, Hedeoma pulegioides and many other essential oils. Fragrance and flavour ingredient. (R)-p-Menth-4(8)-en-3-one is found in many foods, some of which are blackcurrant, pepper (c. frutescens), spearmint, and red bell pepper. Pulegone, the major chemical constituent of Nepeta catariaessential oil which is an aromatic herb, is one of avian repellents[1]. The molecular target for the repellent action of Pulegone in avian species is nociceptive TRP ankyrin 1 (TRPA1). Pulegone stimulates both TRPM8 and TRPA1 channel in chicken sensory neurons and suppresses the former but not the latter at high concentrations[2].

Pulegone belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. It is formally classified as a cyclic ketone although it is biochemically a monoterpenoid as it is synthesized via isoprene units. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes is known to occur mainly through the methyl-erythritol-phosphate (MEP) pathway in plant cell plastids (PMID:7640522 ). Geranyl diphosphate (GPP) is a key intermediate in the biosynthesis of cyclic monoterpenes. GPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Pulegone is a hydrophobic, neutral compound that is insoluble in water. It exists as a clear, colorless oil. There are two isomers of Pulegone (the R and the S isomer), with the R isomer being more common. It is used industrially as a food additive and a perfuming agent. Pulegone has a fresh, minty or peppermint odor and a minty, fruity or green taste. It is found naturally in the essential oils of a variety of plants such as Nepeta cataria (catnip), Hedeoma pulegioides (pennyroyal), and Mentha species. It is also found in a number of plant foods and spices such as blackberryies, black currants, bell peppers, cornmint, rosemary, black tea, thyme, orange mint, peppermint, and spearmint, which makes it a potential biomarker for the consumption of these food products. Pulegone is also one of more than 140 terpenes that are found in cannabis plants (PMID:6991645 ). Pulegone, also known as (+)-(R)-pulegone or (1r)-(+)-P-menth-4(8)-en-3-one, is a member of the class of compounds known as menthane monoterpenoids. Menthane monoterpenoids are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Thus, pulegone is considered to be an isoprenoid lipid molecule. Pulegone is slightly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Pulegone can be found in a number of food items such as globe artichoke, sacred lotus, garden onion, and rubus (blackberry, raspberry), which makes pulegone a potential biomarker for the consumption of these food products. Pulegone can be found primarily in saliva. Pulegone is a naturally occurring organic compound obtained from the essential oils of a variety of plants such as Nepeta cataria (catnip), Mentha piperita, and pennyroyal. It is classified as a monoterpene . (+)-pulegone is the (5R)-enantiomer of p-menth-4(8)-en-3-one. Pulegone is a natural product found in Hedeoma multiflora, Clinopodium dalmaticum, and other organisms with data available. See also: Agathosma betulina leaf (part of). The (5R)-enantiomer of p-menth-4(8)-en-3-one. Pulegone, the major chemical constituent of Nepeta catariaessential oil which is an aromatic herb, is one of avian repellents[1]. The molecular target for the repellent action of Pulegone in avian species is nociceptive TRP ankyrin 1 (TRPA1). Pulegone stimulates both TRPM8 and TRPA1 channel in chicken sensory neurons and suppresses the former but not the latter at high concentrations[2].
