[摘要]：A phytochemical investigation of the cone of Pseudolarix amabilis led to the isolation of pseudolarenone (1), a structurally novel pentacyclic (5/11/5/6/5) nortriterpenoid lactone with an unprecedented carbon skeleton featuring a unique bicyclo[8.2.1]tridecane core. Its structure and absolute configurations were elucidated by spectroscopic analysis and single crystal X-ray diffraction (CuK alpha).
