Terpenoids from Chloranthus serratus and Their Anti-inflammatory Activities

Seven new terpenoids, including two sesquiterpene dimers (1, 2), two norditerpenoids (3, 4), and three sesquiterpenes (5–7), along with six known sesquiterpene dimers and four known sesquiterpenes were isolated from the whole plant of Chloranthus serratus. Their structures and relative configurations were elucidated on the basis of spectroscopic data analysis. The absolute configuration of 1 was determined by the CD exciton chirality method....
