Abstract
An investigation of the rhizomes of Atractylis koreana afforded, in addition to known selinane sesquiterpenoids, an ester of tetradeca-6,
12-diene-8, 10-diyne-1,3-diol and two isomers of 6-methyl-2-geranyl-p-benzoquinone, which are new compounds for the genus Atractylis. Their structures
were established by spectroscopic and chemical methods.
