The essential oils of Brachythecium salebrosum, Eurhynchium pulchellum and Plagiomnium undulatum were investigated by GC-FID and GC-MS. A total of 39 compounds were identified, constituting over 85.2, 80.9 and 88.8 % of total oil composition of B. salebrosum, E. pulchellum and R undulatum and the main components of them were n-nonanal (66.3 and 36.2 %) and gamma-elemene (24.1 %), respectively. Sesquiterpene hydrocarbons (51.7 %) were shown to be the main group of P. undulatum. Aliphatic aldehydes were the major constituents of B. salebrosum and E. pulchellum with the ratio of 73.3 and 57.9 %, respectively.
