Breutelia tomentosa (Sw. ex Brid.) A. Jaeger, Leptodontium viticulosoides (P. Beauv.) Wijk & Margad., Macromitrium perreflexum Steere, Campylopus richardii Brid., Rhacocarpus purpurascens (Brid.) Paris., and Thuidium peruvianum Mitt. essential oils were obtained by hydrodistillation. Using gas chromatography/flame ionization detector (GC/FID) and Gas chromatography/Mass spectrometry (GC/MS), a total of ninety four constituents were identified, representing for 80.5 93.8 % of the chemical composition. The major components were epizonarene (8.7 %) and -selinene (6.7 %) in the oil of B. tomentosa, -selinene (13.5 %) and -selinene (10.5 %) in the oil of L. viticulosoides, selina-3,11-dien-6--ol (19.7 %) and curcuphenol (10.6 %) in the oil of M. perreflexum, epi--muurulol (15.1 %) and -cadinol (12.5 %) in the oil of C. richardii. -cadinol (36.8 %) and -santalene (8.4 %) in the oil of R. purpurascens, and phytol (21.7 %) and valerenol (10.1 %) in the oil of T. peruvianum.
