Abstract

Abstract: A new guaiane-type sesquiterpene lactone, named 3β, 8α, 11α, 13-tetrahydroxy-10 (14 )-guaien-1α, 4β, 5α, 6βH-6α, 12-olide (1) , together with a known sesquiterpene lactone , cynarinin A (2) , were isolated from the leaves of Cynara scolymus (Artichoke). The structure of 1 was elucidated on the basis of MS, IR, 1D, and 2D NMR .

Key words: Cynara scolymus
