Abstract

The chemical composition of the essential oil extracted from fresh leaves of Lippia citriodora (Verbenaceae) was analyzed by GC-FID and GC–MS in May, when growth rates are maximal, and in September, in full bloom. In both samples the main constituents were geranial, neral and limonene constituting 66.3% of the total essential oil yield in May and increasing to 69% in September. Their individual percentage values, however, changed considerably for geranial and neral decreasing from 38.7 to 26.8% and from 24.5 to 21.8%, respectively, and for limonene increasing from 5.8 to 17.7%. All other components remained more or less unchanged both qualitatively and quantitatively. FT-IR spectrometry was also applied for the qualitative determination of the main components.
