A toxic component to mice was isolated from the viscera of cultivated carp (Cvprinus carpio) as white powder. Molecular formula was obtained to be C_(27)H_(48)O_8S on the basis of the HRFABMS data. NMR spectra of the isolated compound were con-esponded with those of 5α-cyprinol except the C26 sulfated carbon. Therefore, it was identified as cyprinol sulfate (5α-cholestane 3α,7α,12α,26,27-pentol 26-sulfate). It showed toxicity to mice (2∼3 ㎎/MU, i.p.), hemolytic activity (500 ㎍/㎖) and prolyl endopeptidase inhibition (IC_(50)$gt; 200 ㎍/㎖), but, had no antibacterial, antifungal and cytotoxic activity to L1210 cells.
