Abstract :
In this study, aerial parts of Lippia citriodora Kunth were harvested at three phenological stages (i.e. vegetative, full
flowering and fruit set). The essential oil isolated by hydro distillation for 3 h using a Clevenger-type apparatus and
the oil was analyzed by GC and GC-MS. The yields of oils (w/w%) in different stages was in the order of: full
flowering (0.9%), vegetative (0.48%) and fruit set (0. 25%). In total, 13, 12 and 11 compounds of essential oil were
identified in vegetative, full flowering and fruit set, respectively. The main compounds in three stages were geranial
and neral. Geranial was highest at vegetative (33.7%) and lowest at full flowering (32.7%) stages. The highest and
lowest neral content was observed at vegetative (26.1%) and fruit set (25.06%) stages, respectively.
