Two new sesquiterpenoids (alpinolide and hanamyol) were isolated from Alpinia japonica (THUNB.) MIQ. and the structures were determined by the spectral, the chemical evidence and X-ray analysis. The chemical transformation of hanalpinol into alpinolide may suggest the biogenesis of furopelargone A and B.
