Green pigments in epidermal blisters of decomposed cadavers

A spectrophotometrical method for discrimination between sulfhemoglobin (SHb) and choleglobin was applied to analyses of the green pigments in epidermal blisters of decomposed cadavers. SHb appeared to be a predominant constituent of the pigments, although significant amounts of choleglobin, one third to one sixth of SHb, were also demonstrated. The present results indicate that the greenish discoloration of decomposed cadavers is due to formation of a mixture of SHb, choleglobin and possibly other denatured hemoglobin derivatives.
