title: Bisabolane-type sesquiterpenes: liginvolones A-D from ligusticum involucratum.
abstract: Four new bisabolane-type sesquiterpenes, liginvolones A-D (1-4), a new coumarin, 4'-octanoyloxyosthenol (5), and 20 known constituents were isolated from Ligusticum involucratum. Their structures were elucidated on the basis of spectroscopic analyses and chemical methods.
