Constituents of the essential oil of lippia integrifolia (Griseb.) Hieron. (Verbenaceae)

The essential oil of Lippia integrifolia was analysed by capillary GC interfaced with MS. The main constituents were isolated by using column chromatography and reversed-phase liquid chromatography and their structures established by spectroscopic methods. The major constituent of the oil is lippifo...
