The essential oils were obtained from roots of Igagayatsuri (Cyperus polystachyos Rottb.), Azegayatsuri (Cyperus globosus Allioni) and Tamagayatsuri (Cyperus difformis L.) by steam distillation in 0.005_??_0.023% yields. The components were separated by means of column chromatography and preparative gas chromatography. Identification of the components was performed on agreement of the tR in GC and mass spectra with those of the authentic specimens. As main components, normal alkanes such as C20H42, C21H44, C22H46, C23H48, C24H50, β-caryophyllene (Tamagayatsuri; T) α-humulene (T), cyperotundone (Igagayatsuri; 1), juniper camphor (I, T), α-cadinol (I, T), methyl 3, 7, 11-trimethyl-ll-hydroxy trans-2, trans-6, trans-9-dodecatrienoate (I), and as a minor one a-copaene (Azegayatsuri; A), α-cedrene (A), δ-cadinene (T), calamenene (A), C16H34 (A), C18H38 (I, A, T), C19H40 (I, A, T), C21H44 (A), methyl 3, 7, 11-trimethyl trans-2, trans-6, cis-9, 11-dodecatetraenoate (T), methyl 3, 7, 11-trimethyl trans-2, trans-6, trans-9, 11-dodecatetraenoate (T), α-cyperone (A), octanol (A), α-terpineol (I), elemol (1, A), nerolidol (A, T), eudesmol (T) were identified.
