Terpenoids from Roots of Chloranthus spicatus

Five new terpenoids, including four eudesmane-type sesquiterpenoids, 1–4, and one labdane-type diterpenoid, 6, together with ten known compounds, were isolated from the roots of Chloranthus spicatus. The structures and their relative configurations were mainly established by 1D- and 2D-NMR spectra, and MS experiments.
