Volatile Constituents of the Roots of Cyperus compressus Linn.

Abstract The essential oil from the roots of Cyperus compressus Linn. (Cyperaceae) collected from south India was analyzed by GC and GC/MS. Twenty-two compounds, representing 90.5% of the oil were identified. The oil has been characterized by the predominance of sesquiterpenoids (89.9%), with caryophyllene oxide (34.0%) and cyperene (25.6%) being the major constituents
