The structure of ceroalbolinic acid, a widely occurring insect pigment, a common body pigment of three Japanese Ceroplastes scale insects, has been confirmed as 2 by 13C-NMR long-range selective proton decoupling (LSPD) experiments on its permethylated derivative 3. Full assignments of skeletal carbons for 3 were also obtained.
