Common Name(2s)-2-[(3e)-4,8-dimethylnona-3,7-dien-1-yl]-2,7-dimethylchromen-5-ol
DescriptionConfluentin belongs to the class of organic compounds known as bicyclic monoterpenoids. These are monoterpenoids containing exactly 2 rings, which are fused to each other. (2s)-2-[(3e)-4,8-dimethylnona-3,7-dien-1-yl]-2,7-dimethylchromen-5-ol is found in Albatrellus flettii, Albatrellus confluens and Baorangia pseudocalopus. (2s)-2-[(3e)-4,8-dimethylnona-3,7-dien-1-yl]-2,7-dimethylchromen-5-ol was first documented in 2003 (PMID: 12761765). Based on a literature review a significant number of articles have been published on confluentin (PMID: 19644795) (PMID: 23305465) (PMID: 32369483) (PMID: 31791817) (PMID: 34854776) (PMID: 22667149).
