Three new norsesquiterpenoids from the seeds of Alpinia galanga.
From the seeds of Alpinia galanga Willd., three new norsesquiterpenoid racemic mixtures, galanols A-C (1-3) were isolated, along with three known sesquiterpenoids (4-6). Their structures were elucidated by means of UV, IR, HR-ESI-MS, 1D NMR and 2D NMR spectroscopic data.
