title: Guaiane-type sesquiterpenoids from Alisma orientalis.
abstract: Two guaiane-type sesquiterpenoids named orientalol E (1) and orientalol F (3) were isolated from the rhizome of Alisma orientalis (SAM) JUZEP together with two known guaiane-type sesquiterpenoids alismol (2) and alismoxide (4). Their relative stereostructures were elucidated by spectroscopic methods, whereas absolute stereostructures were determined on the basis of chemical correlation.
