Description | Taraxerol, also known as alnulin, is a naturally-occurring pentacyclic oleanane-type triterpenoid. It can be found in plants such as Taraxacum officinale (Asteraceae; dandelion), Alnus glutinosa (Betulaceae), Litsea dealbata (Lauraceae), Skimmia spp. (Rutaceae), Dorstenia spp. (Moraceae), Maytenus spp. (Celastraceae), and Alchornea latifolia (Euphobiaceae). Taraxerol is an oleanan-3-ol with an alpha-methyl substituent at position 13, a missing methyl group at position 14, and a double bond between 14 and 15. A large number of medicinal plants are known to have this compound in their leaves, roots or seed oil (PMID: 26009688 ). Taraxerol has shown the anti-inflammatory effects in vitro, it can disrupt the activation of the enzymes MAP3K7 (TAK1), protein kinase B (PKB or Akt), and NF-κB. By doing so, it may inhibit the expression of proinflammatory mediators in microphages (PMID: 23333629). Taraxerol also exhibits anti-carcinogenic activity. In vivo two-stage carcinogenesis tests of mouse skin tumor showed that taraxerol can inhibit the induction of Epstein-Barr virus early antigen (EBV-EA) by the tumor initiator 7,12-dimethylbenz(a)anthracene (DMBA) and the tumor promoter 12-O-tetradecanoylphorbol-13-acetate (TPA) (PMID: 10408235 ) (Wikipedia ). Taraxerol is found in alcoholic beverages. |
