The oil is primarily used as a source in production of perfumery chemicals such as citronellal and citronellol.
The main components of the oils were citronellal (35.47%; RI = 1154), geraniol (21.83%; RI = 1256), and citronellol (10.94%; RI = 1229) in C.
While Cymbopogon winterianus presents 38% citronellal, 12% citronellol and 22% geraniol.
Smell training consisted of twice-daily exposure to four intense odors (phenylethyl alcohol, eucalyptol, citronellal, and eugenol).
