The essential oils from roots of Shitito (Cyperus monophyllus Vahl) have been studies.
The essential oils were separated into individual compounds by means of combination of elution chromatography and preparative gas chromatography (GC).
The main components, trans-pinocarveol, trans-carveol, pinocaroone, myrtenol, myrtenal, verbenone, β-selinene, δ-cadinene, juniper camphor, trans, trans-farnesol, methyl trans-2, trans-6-farnesate, α-cyperone, trans-2, trans-6-farnesyl acetate; and the minor ones, α-pinene, camphene, limonene, p-cymene, linalool, cyperene, β-caryophyllene, α-cadinol were identified respectively in terms of tR in GC, MS and IR spectra.
