Droserone (2,5-dihyrdoxy-3-methyl-1,4- naphthoquinone) was prepared from naturally occurring naphthoquinone plumbagin. Plumbagin was isolated from roots of Plumbago zeylanica. Plumbagin was first brominated at C-3 which was subsequently substituted with hydroxy group by a nucleophilic substitution to obtain Droserone. The synthesized compounds were characterized by IR, MS, 1H and 13C NMR spectral data. RP-HPLC was used to ascertain the purity of the obtained compound.
