ABSTRACT


To verify the composition variation of its essential oil along 24 hours, leaves of Lantana camara  Linn. of medicinal plant collection of the Department of Chemical Biology of URCA-Crato–CE, were collected every three hours during one day (of the 07:00 to 19:00 h) in April, 2008. The leaves had its oil extracted by hydro-distillation in Clevenger apparatus during three hours with two repetitions. The chemical composition analysis of the extracted essential oils was carried out in gas chromatography/mass spectroscopy. The phytochemical profile of the essential oils presented significant difference in function of the harvest. The seven most abundant were: germacrene D (24.50-6.15%), biciclogermacrene (33.32-14.27%), spathulenol (25.04-1.06%), eremophilene (20.64-1.93%), valecene (33.70-0.84%), viridiflorene (19.46%) and 1,10-di-epi-cubenol (27.93-21.32). The different result found here indicates the existence of different chemotypes of L. camara
