摘要：

RP-18 chromatography of the methanolic extract of the leaves of Haplopappus foliosus D.C. led to the isolation of (1 alpha,7 beta,10 beta)-11-hydroxy-4-guaien-3-one and the two new isomeric guaianes: (1 beta,7 beta,10 beta)-1,11-dihydroxy-4-guaien-3-one and (1 alpha,6 alpha,7 beta,10 beta)-6,11-dihydroxy-4-guaien-3-one. The structure and relative configurations of the new compounds are proposed on the basis of spectroscopic evidence. (C) 1998 Elsevier Science Ltd. All rights reserved.
