英文摘要	Five new diarylbutyrolactones and sesquilignans ( 1a/1b - 4 ), including one pair of enantiomers ( 1a/1b ), together with 10 known analogues ( 5 - 14 ), were isolated from the whole plants of Saussurea medusa . Compound 1 was found to possess an unusual 7,8 ' -diarylbutyrolactone lignan structure. Separation by chiral HPLC analysis led to the isolation of one pair of enantiomers, (+)- 1a and (-)- 1b . The structures of the new compounds were elucidated by extensive spectroscopic data. All compounds, except compounds 5, 7 and 9 , were isolated from S. medusa for the first time. Moreover, compounds 1 - 4, 8 and 10 - 14 had never been obtained from the genus Saussurea previously. Compounds (+)- 1a, 2, 5, 7 , and 9 - 11 were found to inhibit the lipopolysaccharide (LPS)-induced release of NO by RAW264.7 cells with IC (50) values ranging from 10.1 +/- 1.8 to 41.7 +/- 2.1 mu M. Molecular docking and iNOS expression experiments were performed to examine the interactions between the active compounds and the iNOS enzyme.
