Zeylanone and isozeylanone have been shown to be novel dimers of plumbagin (2-methyl-5-hydroxy-1,4-naphthaquinone). A probable mode of their formation in vivo from plumbagin (1) and its hydroquinone (3) has been postulated (Scheme 1). Benzene induced solvent shifts of the aromatic protons of zeylanone have been discussed.
