Common Name(4as,4br,7s,8ar,10as)-7-ethenyl-1,1,4a,7-tetramethyl-decahydrophenanthren-8a-ol
DescriptionNezukol belongs to the class of organic compounds known as diterpenoids. These are terpene compounds formed by four isoprene units. (4as,4br,7s,8ar,10as)-7-ethenyl-1,1,4a,7-tetramethyl-decahydrophenanthren-8a-ol is found in Cryptomeria japonica, Manoao colensoi and Prumnopitys andina. (4as,4br,7s,8ar,10as)-7-ethenyl-1,1,4a,7-tetramethyl-decahydrophenanthren-8a-ol was first documented in 1988 (PMID: 24276129). Based on a literature review a small amount of articles have been published on nezukol (PMID: 23714012) (PMID: 28445526).
