Keywords:
Roldana ehrenbergiana, asteraceae, senecioneae, hierba del perro, seco-eremophilanolidesAbstract
Abstract. Two new seco-eremophilanolides, roldehrenbergins C and D, were isolated from Roldana ehrenbergiana. Structural elucidation was achieved by spectroscopic methods and confirmed by X-ray crystallographic analysis.
