In the caraway fruit, d-carvone is biosynthesised through a multi-step pathway starting from geranyl diphosphate which is firstly cyclised to d-limonene, then stored in essential oil ducts, further converted to d-trans-carveol by limonene-6-hydroxylase, and finally oxidised by a dehydrogenase to d-carvone (Bouwmeester et al., 1998). In a similar fashion, l-carvone is synthesised in the glandular trichomes of spearmint (Mentha spicata) through the cyclisation of the C10 isoprenoid intermediate geranyl pyrophosphate to the monoterpene hydrocarbon l-limonene then hydroxylated to l-carveol and subsequently dehydrogenated to l-carvone (Gerchenzon et al., 1989) [1].

Activities in the field of food flavourings Regarding the evaluation of carvone in food, the genotoxicity of d-carvone was evaluated by the JECFA; it was concluded that d-carvone was not genotoxic and was not carcinogenic in mice. This evaluation of the JECFA was endorsed by the CEF Panel and d-carvone together with the structurally related l-carvone were cleared with respect to genotoxicity (EFSA CEF Panel, 2011a). Considering that the JECFA evaluated the two substances before 2000 and that no safety concerns were identified by the JECFA, EFSA was not required to re-evaluate their safety, in line with the provisions laid down in Commission Regulation (EC) No 1565/20006 . Accordingly, both substances were included in the European Union list of flavouring substances in Regulation (EU) No 872/2012 (EU, 2012) [1].

16724 rabbit LD50 skin 4 mL/kg SKIN AND APPENDAGES (SKIN): DERMATITIS, OTHER: AFTER SYSTEMIC EXPOSURE Food and Cosmetics Toxicology., 16(673), 1978 The Committee did not re-evaluate (+)-carvone (No. 380.1) according to the revised Procedure for the Safety Evaluation of Flavouring Agents given the lack of information on the oral exposure from all sources and the need to review the ADI. A review of the ADI is recommended based on the evaluation of all biochemical and toxicological data. Also, data are needed for an exposure assessment for oral exposure to (+)-carvone from all sources to complete the evaluation for (+)-carvone. |

| Additional Infomation |
D-carvone appears as pale yellow or colorless liquid. (NTP, 1992)
(+)-carvone is a carvone having (S) configuration. It is an enantiomer of a (-)-carvone. d-Carvone has been reported in Camellia sinensis, Angelica gigas, and other organisms with data available. See also: Caraway Oil (part of). Carvone is a natural component in several food items such as mint and caraway but it may also be used as a pesticide, food flavouring, feed flavouring or, together with other active substances, in a zootechnical feed additive. Evaluations of this compound have therefore been performed by different scientific bodies and by the European Commission: initially by the Joint FAO/WHO Committee on Food Additives (JECFA) between 1968 and 2000, then as a pesticide active substance by the European Commission in 2008 (in application of Directive 91/414/EEC4 , repealed by Regulation (EC) No 1107/20095 ), then by the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) in 2011 and the latest evaluation by EFSA's Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) in 2011. The JECFA established an acceptable daily intake (ADI) of 0-1 mg/kg body weight per day based on short-term studies in rats (WHO, 2000, 2004). The Standing Committee on the Food Chain and Animal Health (SCoFCAH) of the European Commission (EC) established an ADI of 0-0.025 mg/kg bodyweight per day based on a different short-term toxicity study in rats (EC, 2008), the CEF and FEEDAP Panels endorsed the assessment done by the JECFA. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
