Özet: The phytochemical study of the chloroform soluble part of the hydroalcoholic extract of Marrubium deserti allowed us to describe a new labdane diterpene, 6-dehydroxy-19-acetyl-marrubenol (3) beside three other diterpenes : 19-acetyl-marrubenol (6) , 6-acetyl-marrubenol (7) and 16-epoxy-9-hydroxy-labda-13(16), 14- diene (1). This latter derivative is described for the first time as natural compound. Phytol (2), and three sterols: b -sitosterol (4), stigmasterol (5) and b -sitosterol 3-O-glucoside (8) were also isolated from this species. Structure elucidation of the isolated compounds was accomplished by means of spectroscopic techniques, especially NMR spectroscopy and mass spectrometry.
