Cymbopogon nardus (serai wangi) essential oils or commercially known as citronella oil have long been utilised as perfumery ingredients in toiletries and insect repellent products. As part of a study in promoting the use of locally produced citronella oils in product formulations, the essential oils of C. nardus (serai wangi) collected from two locations (Gua Musang and Bukit Hari) were examined by a combination of GC and GC/MS. The essential oils were made up of various chemical components that included monoterpene alcohols, sesquiterpenes and acetates with the major components being citronellal, citronello] and geraniol. Although the chemical composition of all of the oils studied was similar, it differed quantitatively. Citronellal was the most abundant chemical component in some of the Gua Musang oils while the Bukit Hari oils were characterised by higher amounts of geraniol content. Evaluation on the toxicity of the citronella oils against the 3rd to 4th instar larvae of a vector mosquito (Aedes aegypti) showed a stronger activity in the Gua Musang oils compared to the Bukit Hari oils.
