Sensory and Chemical Evaluation of Tropical Grass Oils

To this family belongs a group of aromatic tropical grasses of the genus Cymbopogon, which comprises about 40 species. Some of the Cymbopogon species are imporant for the production of essential oils. The most important essential oils isolated from the Cymbopogon species are:

Citronella oils from Cymbopogon nardus (L,) Rendle and from Cyrnbopogon winterianus Jowitt.

Lemongrass oil from Cymbopogon citratus (DC.) Stapf, or Cymbopogon flexosus Stapf.
