The essential oil of leaves and peels of Ocimum gratissimum, Cymbopogon citratus,
Hyptis suaveolens, Eucalyptus globulus, Azadirachta indica and Citrus sinensis were
extracted and then formulated in a complex solution. Constituent analysis of the
repellent formulation was conducted using Gas Chromatography (GC). A total of
seven compounds were detected representing 99.92% of the essential oil components
of the repellent formulation. The major component present was limonene (34.91%)
and the other main components were salanine (4.34%), citral (22.64%), 1,8 – cineole
(7.00%), citronella (17,49%), caryophyllene (11.25%) and azadirachtin (2.29%). The
present study showed the potential of volatile compounds of plants as possible
constituents of repellent products.
