The composition of the essential oil of Cymbopogon citratus, obtained
in semiindustrial scale, has been analyzed by gas chromatography Reten
tion index, relative retention time, and co-chromatography with pure c
ompounds were applied. Components were also characterized by mass spec
trometry: The identified compounds make more than the 96% of the essen
tial oil. Results were qualitatively and quantitatively compared with
the composition found in oils of Cymbopogon citratus and Cymbopogon fl
exuosus from other producing zones.
