Abstract
The acid hydrolysis of the total glycosides from the holothurianDuasmodactyla kurilensis Levin. has yielded a new aglycone which has been called kurilogenin. On the basis of the results of NMR, IR, UV, and mass spectroscopy, it has been shown that it is 3β-hydroxy-4,4,14-trimethylpregna-9(11),16-dien-20-one.
