Common Name(4bs,8as)-2-hydroxy-1-isopropyl-4b,8,8-trimethyl-5,6,7,8a-tetrahydrophenanthrene-3,9-dione
DescriptionMaytenoquinone belongs to the class of organic compounds known as oxosteroids. These are steroid derivatives carrying a C=O group attached to steroid skeleton. (4bs,8as)-2-hydroxy-1-isopropyl-4b,8,8-trimethyl-5,6,7,8a-tetrahydrophenanthrene-3,9-dione is found in Harpagophytum procumbens. (4bs,8as)-2-hydroxy-1-isopropyl-4b,8,8-trimethyl-5,6,7,8a-tetrahydrophenanthrene-3,9-dione was first documented in 2008 (PMID: 18310937). Based on a literature review very few articles have been published on Maytenoquinone.
