摘要：Five new cycloartane triterpenoids, schiglausins K-O (1-5), including one hexanortriterpenoid (1) and one octanortriterpenoid (2), as well as two known compounds (6-7), were isolated from the stems of Schisandra glaucescens Diels. Their structures were elucidated on the basis of spectroscopic methods, including extensive NMR spectra. Compounds 2-7 were tested for their FXR agonistic and antagonistic effects. Compound 7 exhibited significant antagonistic effect against FXR with IC50 of 1.50 mu M. (C) 2012 Elsevier B.V. All rights reserved.
