A new alpha-methylene gamma-lactone sesquiterpene from Hedyosmum arborescens

Fitoterapia. 2005 Dec;76(7-8):620-4. doi: 10.1016/j.fitote.2005.06.006.

Abstract

A new sesquiterpene lactone, 7alpha,10alpha-epoxy-1alpha(H),5alpha(H)-guaia-3,11(13)-dien-8alpha,12-olide, was isolated from the leaves of Hedyosmum arborescens. The structure of this unusual 7,10-epoxy-guaianolide was determined by spectroscopic methods, particularly one- and two-dimensional 1H and 13C NMR.
