1. Bile salts of carp, Cyprinus carpio, when hydrolyzed with trichloroacetic acid in dioxane solution yielded cyprinol as a chief component, which is believed to be 3α, 7α, 12α, 26, 27-pentahydroxycholestane on the baisis of the nuclear magnetic resonance spectroscopic data and on the fact that 3α, 7α, 12α-trihy-droxy-26, 27-epoxycholestane was derived from cyprinol sulfate.
2. The presence of cholic acid in carp bile was confirmed.
The authors wish to thank Dr. K. Takeda, Director of Shionogi Research Laboratory, Osaka, for his generous help in determination and interpretation of nuclear magnetic resonance spectra, and Prof. G. A. D. Haslewood, Guy's School of Medicine, London, for his notification of unpublished work and for his helpful discussion.
