title: Guaiane-type sesquiterpenes from Curcuma wenyujin and their inhibitory effects on nitric oxide production.
abstract: Four new guaiane-type sesquiterpenes (1S,4S,5S,10R)-zedoarondiol, zedoalactones D, E, and F (1-4), along with 10 known ones (5-14), were isolated from Curcuma wenyujin Y.H. Chen et C. Ling. The structures of these new compounds were elucidated by spectroscopic methods. The inhibitory effects of compounds 1-14 on nitric oxide production in lipopolysaccharide-activated macrophages were evaluated.
