Abstract

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.
