title: Chemical constituents from Alpinia tonkinensis.
abstract: Two new compounds, 2 alpha-(p-hydroxycinnamoyl) cineole (2) and (E)-15-nor-16-oxo-8(17),12-labdadiene (4), along with three known compounds, trans-cinnamyl methyl ester (1), 4(15)-cadinene-6,10-diol (3) and isorhamnetin-3-O-beta-D-galactosyl-(6-->1)-alpha-L-rhamnoside (5), have been isolated from Alpinia tonkinesis Gangep. Their structures have been elucidated by spectral analysis.
