„Tarchonanthus camphoratus wood is fragrant, close-grained, attractive, durable and rich in aromatic oils… Leleshwa is also a source of aromatic oils used as fragrances. Its leaves are used by the Maasai to scent their homes and persons.“ https://en.wikipedia.org/wiki/Tarchonanthus_camphoratus
Main components of the leaf oil were α-fenchol (29.1%), 1,8-cineole (16.5%) and α-terpineol (8.5%).

Main components of the essential oil (steam distillation) of leaves and flowersheads of T.camphoratus growing wild in Kenya were α-pinene (16.8%), 1.8-cineole (13.0%), α-fenchol (10.8%), α-fenchene/camphene (8.2%), α-terpineol (4.2%), β-pinene (3.7%), δ-2-carene (3.2%), and cis-p-menth-2-en-1-ol/trans-pinene hydrate (3.1%).
Strongest odor impressions in GC-O made α-pinene, myrcene, 1.8-cineole, fenchone, α-fenchol, trans-verbenol, camphene hydrate, and fenchyl acetate.
