Epicuticular wax accounted for 9.2% of the dry wt. of whole Flourensia cernua (tarbush) leaves. Leaf surface extracts of tarbush were analyzed for mono- and sesquiterpenoids with gas chromatography-mass spectrometry. Camphene, beta-myrcene, 3-carene, limonene, 1,8-cineole, borneol, cis-jasmone, beta-caryophyllene, caryophyllene oxide and globulol were consistently present on the leaf surface of tarbush. Concentrations of several unidentified compounds were estimated. A great deal of plant-to-plant variability was detected in leaf surface mono- and sesquiterpenoid concentration. Information obtained on surface chemistry might be exploited to enhance the use of tarbush as a forage for domestic herbivores.
