Chemical study of the essential oil of Cyperus rotundus

Phytochemistry. 2001 Nov;58(5):799-810. doi: 10.1016/s0031-9422(01)00301-6.

Abstract

Minor constituents of the essential oil of Cyperus rotundus have been investigated. The three new sesquiterpene hydrocarbons (-)-isorotundene, (-)-cypera-2,4(15)-diene, (-)-norrotundene and the ketone (+)-cyperadione were isolated and their structures elucidated. The absolute configuration of (-)-rotundene was derived by chemical correlation and enantioselective gas chromatography.
