Two new germacrane‐type sesquiterpene lactones, curdionolides A and B ( 1 and 2 , resp.), and a novel germacrane‐type sesquiterpene lactam, curdionolide C ( 3 ), were isolated from Curcuma wenyujin. Y. H. Chen et C. Ling together with five known germacrane‐type sesquiterpenes, 4 – 8 . The structures of the new compounds were elucidated by spectroscopic methods. The inhibitory effects of compounds 1 – 8 on nitric oxide (NO) production in lipopolysaccharide‐activated macrophages were evaluated.
