Abstract
A new sesquiterpene lactone of the eudesmane series, mucrolide, has been isolated from the epigeal part ofTanaceptopsis mucronata and its constitution has been established on the basis of chemical transformations and IR, mass, and PMR spectra. Its spatial structure has been reliably determined by x-ray structural analysis as 1β,6α-dihydroxy-5α,7α(H)-eudesmane-3,11(13)-dien-8,12-olide.
