Cynaratriol, a new guajanolide from Cynara cardunculus L. and C. scolymus L. (Compositae)A new guajanolide given the name cynaratriol (4) was isolated from the leaves of Cynara cardunculus L The structure of 4 and its derivatives 3, 11, 13-triacetylcynaratriol (5) and 3, 13-dibenzoyl-cynaratriol (6) was deduced on the basis of IR.-, 1H-NMR.-, 13C-NMR.- and mass spectroscopic data. 4 is also present in C. Scolymus L. as shown by GC./MS. analysis. The same absolute configuration is suggested for 4 as found for all other Cynara sesquiterpenes.
