-The primary essential oil (0.3-0.8%) consists mainly of geraniol (78.0-85.7%) and geranyl acetate (2.9-12.0%). Minor components were linalool (2.2-2.4%), (E,Z)-farnesol (0.8-1.9%), sabinene, myrcene, limonene, (Z)-β-ocimene, (E)-β-ocimene, citronellol, geranyl butyrate, geranyl isovalerate, and geranyl hexanoate. \\
+Main components of palmarosa EO are geraniol (up to 80%) and closely biogenetically related compounds like linalool, neral, geranial and a series of geraniol esters. Alkyl-substituted pyrazines and pyridines present in traces (total 100ppm; more than 40 different nitrogen-containing compounds) are responsible for the rye bread notes. Main constituents of the basic fraction are trimethyl- and tetramethylpyrazine. \\

+Qualitative sensory properties of the essential oil are: sweet floral, geraniol-(rose-)like with herbal, tea, rye bread and clary sage notes. Main components of oil from India, Brazil, Guatemala and Madagascar were geraniol (59-94%), geranyl acetate (5-20%), geranyl formate (0-15%), nerol (0-14%), and linalool (0-12%). Minor components were e.g. nerolidol, farnesol, limonene, ocimene, γ-terpinene, elemol and β-caryophyllene.  \\
