Terpenoids from roots of Chloranthus henryi.

Six new terpenoids, including three diterpenoids (1-3), one norditerpenoid (4) and two sesquiterpenoids (11 and 12), were isolated from the roots of Chloranthus henryi. The structures were elucidated mainly by 1D, and 2D NMR and MS experiments, and their relative configurations were determined by NOE techniques.
