Leaf oils of the genus Acradenia (Rutaceae)

The leaf oils of two species of Acradenia were found to vary with the locat ion of the collection. A. euodiiformis (F. Muell.) leaf gave 0.02-0.20%(w/w ) of an essential oil rich in either monoterpenes (alpha -pinene (16%), lim onene (8%) and p-cymene (13%)) or sesquiterpenes [aromadendrene (11-22%), c aryophyllene oxide (4-13%), globulol (11-13%) and spathulenol (12-18%)]. A. frankliniae Kippist leaf gave 1.2-3.0% (w/w) oil containing either xanthox ylin (90%) or monoterpenes alpha -pinene (19-21%), camphene (13-14%), beta -pinene (24-25%) and (E)-beta -ocimene (8-10%) as major components.
