• <SUP>3</SUP>H-luteoskyrin was injected subcutaneously into male and female mice and its radioactive compounds in the liver and excreta were analyzed. The radioactive compounds in the subcellular fractions of the liver could be extracted into ether under acidic conditions, and those in the excreta were recovered by extraction with ethanol. One of the radioactive compounds isolated from the liver and the feces was identified as unmetabolized <SUP>3</SUP>H-luteoskyrin by thin-layer chromatography, gel filtration and spectrophotometry. In the liver subcellular fractions, mitochondria and cell debris contained <SUP>3</SUP>H-luteoskyrin almost exclusively, while in the postmitochondrial fraction <SUP>3</SUP>H-luteoskyrin corresponded to one half of the total radioactive compounds. The urine contained radioactive compounds other than <SUP>3</SUP>H-luteoskyrin one of which was separated by the gel filtration. It was concluded that, after preferential distribution in the subcellular fractions, especially in the mitochondria and cell debris, of the liver, luteoskyrin is excreted as such in the feces and as a metabolite in the urine.
