Abstract
A new ecdysteroid with the composition C27H44O6 which has been called brahuisterone has been isolated from the epigeal part of the plantSilene brahuica Boiss. Its chemical and complete spatial structures have been established by spectral studies and the x-ray structural method (diffractometer, Cu-Kα radiations, 996 reflections, direct method, R=0.119).
