Eudesmane‐Type Sesquiterpene Derivatives from Saussurea conica

Four new eudesmane‐type sesquiterpene derivatives, 3 β ‐[( β ‐ D ‐glucopyranosyl)oxy]‐11 α H‐eudesm‐4(14)‐en‐12,8 β ‐olide ( 1 ), (3 β )‐eudesma‐4(14),11(13)‐diene‐3,12‐diol ( 2 ), 3 β ‐[( β ‐ D ‐glucopyranosyl)oxy]eudesma‐4(14),11(13)‐dien‐12‐ol ( 3 ), and 3 β ‐[( β ‐ D ‐glucopyranosyl)oxy]eudesm‐4(14)‐en‐11‐ol ( 4 ), together with the known (3 β )‐eudesm‐4(14)‐ene‐3,11‐diol ( 5 ) were isolated from Saussurea conica , and their structures were elucidated both spectroscopically and by chemical methods.
