A new biphenylpropanoid, katsumadin (1), together with seven known ones cardamonin (2), (4 E , 6 E )‐1,7‐diphenyl‐4,6‐heptadien‐3‐one (3), pinocembrin (4), (4 Z , 6 E )‐5‐hydroxy‐1,7‐diphenyl‐4, 6‐heptadien‐3‐one (5), 7,4î‐dihydroxy‐5‐methoxyflavanone (6), 3,5‐dihydroxystilbene (7), and alpinetin (8) were isolated from the seeds of Alpinia katsumadai Hayata and identified based on detailed spectral analysis including 2D NMR spectrometry and HRMS. Compounds 1‐4 and 8 showed antiemetic activity.
