Spicachlorantins C-F (1-4), new lindenane-sesquiterpene dimers possessing a hydroperoxy group, were isolated from the roots of Chloranthus spicatus. Their structures, including the absolute stereostructures, were established by 1D and 2D NMR, as well as CD spectroscopic analyses. Spicachlorantins C-F were considered to be biogenetic precursors for the corresponding hydroxy derivatives of dimeric lindenane sesquiterpenes distributed in Chloranthus plants.
