Abstract

Three novel eudesmane-type sesquiterpenes, 10-epi-5β-hydroperoxy-β-eudesmol (I), 10-epi-5α-hydroperoxy-β-eudesmol (II) and 4, 10-epi-5β-hydroxydihydroeudesmol (III), have been isolated from the rhizomes of Alpinia japonica. Their structures were determined by spectroscopic methods and chemical conversions.
