Isolation and Identification of the Urinary Pigment Uroerythrin

European Journal of Biochemistry, 1975
The red pigment uroerythrin, a chromophore known to be adsorbed by the amorphous urate sediments (sedimentum lateritium), has been isolated from human urine and further purified as its trimethyl derivative.Urine was applied to a column of Amberlite XAD‐2 resin on which uroerythrin and other pigments were adsorbed. The pigments were eluted with methanol

Identification of Oxysterols in Human Bile and Pigment Gallstones

Gastroenterology, 2001
Although cholesterol is the most abundant sterol in animal tissues, oxidized products of cholesterol (oxysterols) also occur in mammalian organs and blood and are cytotoxic, atherogenic, and carcinogenic. However, the presence of oxysterols in bile or gallstones has never been reported.Fresh human bile and gallstones were collected.
