Article abstract of DOI:10.1021/jo01291a023

Extraction of Eupatorium mikanioides Chapm. yielded a group of 2-hydroxy-8-(acyloxy)-trans,trans-1-(10),4-germacradienolides related to the antileukemic sesquiterpene lactone deacetyleupaserrin (1c) which was also isolated.Absolute configurations were established by X-ray crystallography of one of the constituents (1e) which had an unprecedented thiol-containing ester side chain.The flavone eupatorin was also isolated.
