Roseanolone is a new diterpene from the African plant Hypoestes rosea (Acanthaceae). The isolation is described; the structure has been determined to be 1,2,3,3a,4,5,6,6a,7,8,9,10a-dodecahydro-5-hydroxy-3-isopropyl-3a, 6-oxa-6,9,10a-trimethyl-dicyclopenta[a,d] cycloocten-1-one by X-ray crystallography.
Sz.wzmary Four known anthraquinones, and a new compound oruwal which was characterized as 9,lO-dimethoxyanthracene-2-carbaldehyde from spectroscopic evidence and chemical transformation were isolated from Morinda lucida Benth. (Rubiaceae) ; oruwal is a possible intermediate in the biosynthetic route to some anthraquinones.
Morinda lucidaBenth., known in the Western State of Nigeria as Oruwo, is a valuable tree used as a dye, and ir, native medicine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
