| Description | Alpha-Cedrene, also known as a-cedrene, belongs to the class of organic compounds known as cedrane and isocedrane sesquiterpenoids. These are sesquiternoids with a structure based on the cedrane or the isocedrane skeleton. Cedrane is a tricyclic molecules a 3,6,8,8-tetramethyl-1H-3a,7-methano-azulene moiety. Isocedrane is a rearranged cedrane arising from the migration of methyl group moved from the 6-position to the 4-position. Thus, alpha-cedrene is considered to be an isoprenoid. Alpha-Cedrene is a sweet, cedar, and fresh tasting compound. Alpha-Cedrene is found, on average, in the highest concentration within safflowers (Carthamus tinctorius). Alpha-Cedrene has also been detected, but not quantified in, several different foods, such as common sages (Salvia officinalis), wild celeries (Apium graveolens), rabbiteye blueberries (Vaccinium virgatum), tarragons (Artemisia dracunculus), and sweet basils (Ocimum basilicum). This could make alpha-cedrene a potential biomarker for the consumption of these foods. Alpha-Cedrene is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. (-)-alpha-Cedrene is found in Acorus calamus, Eupatorium adenophorum , Artemisia annua, Artemisia herba-alba, Asarum simile, Cupressus funebris Endl., Curcuma wenyujin , Juniperus horizontalis, Juniperus procera, Juniperus thurifera, Osyris quadripartita, Persicaria minor, Sideritis athoa, Tagetes filifolia, Thuja occidentalis , Thymus citriodorus, Tordylium apulum, Trachyspermum anethifolium and Vitis vinifera. (-)-alpha-Cedrene was first documented in 1993 (PMID: 16348930). Based on a literature review very few articles have been published on alpha-Cedrene. |
