Common Nametrans-Rose oxide
DescriptionRose oxide, also known as fema 3236 or rose oxide levo, belongs to the class of organic compounds known as oxanes. Oxanes are compounds containing an oxane (tetrahydropyran) ring, which is a six-member saturated aliphatic heterocycle with one oxygen atom and five carbon atoms. Rose oxide can be produced industrially beginning with photooxygenation of citronellol to give the allyl hydroperoxide which is then reduced with sodium sulfite to provide the diol. Rose oxide is an extremely weak basic (essentially neutral) compound (based on its pKa). Rose oxide is an organic compound of the pyran class of monoterpenes. Rose oxide is a fresh, geranium, and green tasting compound. Outside of the human body, Rose oxide is found, on average, in the highest concentration within lemon balms and peppermints. Rose oxide has also been detected, but not quantified in, a few different foods, such as black elderberries, cucumbers, and gingers. This could make rose oxide a potential biomarker for the consumption of these foods. It also contributes to the flavor of some fruits, such as lychee, and wines, such as Gewürztraminer. Ring-closure with sulfuric acid forms both the cis- and trans-isomers in equal amounts. Rose oxide is a fragrance chemical found in roses and rose oil. trans-Rose oxide is found in Aloysia triphylla, Citrus limon, Corymbia citriodora, Cryptomeria japonica, Daphne odora, Magnolia kobus, Paeonia lactiflora, Pelargonium graveolens, Pelargonium quercifolium, Pelargonium vitifolium, Pimenta racemosa, Rosa centifolia, Rosa damascena and Swertia japonica. trans-Rose oxide was first documented in 1999 (PMID: 10564036). The compound has a cis- and a trans-isomer, each with a (+)- and (−)-stereoisomer, but only the (−)-cis isomer (odor threshold 0.5 Ppb) is responsible for the typical rose (floral green) fragrance (PMID: 18247534) (PMID: 23122727) (PMID: 24518327) (PMID: 25212332) (PMID: 25911965) (PMID: 26126958).
