Composition of the Essential Oils of Cistus ladaniferus and C. monspeliensis from Morocco

Abstract The essential oils of Cistus ladaniferus L. var. maculatus Dun. and Cistus monspeliensis L., harvested from northern Morocco, have been analyzed by GC-FID, GC/MS, and NMR techniques. The main components of C. ladaniferus were bornyl acetate, pinocarveol, and viridiforol, whereas the main component from C. monspeliensis was the oxygenated labdane diterpenoid 13-epi-manoyl oxide.
