Leaf Oils of the Genus Acradenia (Rutaceae)

Abstract

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