Phytochemical investigation of the seeds of Alpinia katsumadai (Zingiberaceae) led to the isolation and identification of six new diarylheptanoid derivatives, katsumains D–G ( 1 – 4 ), 3‐(acetyloxy)‐alpinikatin ( 5 ), and 5‐(acetyloxy)alpinikatin ( 6 ). The structures of 1 – 6 were elucidated by spectroscopic data analysis including 1D‐ and 2D‐NMR experiments.
