| Abstract: | A new diterpene, (7α,11β,14β,16R)‐7,11,14‐trihydroxy‐ent‐kaur‐15‐one ( 1 ), and a new sesquiterpene, polyanthuslide ( 2 ), were isolated from the Chinese liverwort Chiloscyphus polyanthus. Their structures were determined on the basis of extensive spectroscopic analyses, and the configuration of 2 was established by X‐ray crystallographic analysis. |
