The essential oils were obtained from roots of Kogomegayatsuri (Cyperus Iria L.) by steam distillation in 0.050_??_0.108%. The components were separated by means of elution and preparative gas chromatography. Identification of the known compounds were performed on agreement of the tR in GC and MS spectra with those of the authentic specimens. The structure of new compounds were determined on the ground of chemical and spectral evidence. As main components, cyperene, caryophyllene, γ-cadinene, caracolene, α-cadinol, cis-3, cis-5-dodecadienyl acetate [1], methyl 3, 7, 11-trimethyl trans-2, trans-6, cis-9, 11-dodecatetraenoate, methyl 3, 7, 11-trimethyl trans-2, trans-6, trans-9, 11-dodecatetraenoate, methyl 3, 7, 11-trimethyl-11-hydroxy trans-2, trans-6, cis-9-dodecatrienoate, methyl 3, 7, 11-triemthyl-11-hydroxy trans-2, trans-6, trans-9-dodecatrienoate, and as a minor one, α-pinene, β-pinene, limonene, p-cyment, linalool, α-copaene, β-elemene, humulene, α-elemene, β-selinene, germacurene-D, γ-muurolene, δ-cadinene, calamenene, juniper camphor, cis-3, cis-5-dodecadien-1-ol [2], methyl 3, 7, 11-trimethyl trans-2, trans-6, 10-dodecatrienoate, C20H42, C21H44, C22H46, C23H48, C24H50 were identified. The separated [1] and [2] were new compounds.
