A new labdane diterpene, amentotaxin A ( 1 ), and an unprecedented dinorlabdane diterpene, amentotaxin B ( 2 ), were isolated from the stems of Amentotaxus argotaenia (Hance) Pilger , together with seven known compounds. Their structures were identified by in‐depth spectroscopic and mass‐spectrometric analyses.
