 Title    of Jojoba (Simmondsia chinensis [Link] Schneider)  
 Abstract    Epicuticular waxes were extracted with hexane from dry Jojoba pericarp and seed. These cuticular waxes consisted of hydrocarbons, wax esters, free acids, free alcohols and sterols; additionally aldehydes were found in the wax obtained from seed coats. The hydrocarbon fraction contained a homologous series of «-alkanes and branched alkanes but no alkenes. The composition of the wax esters of the cuticular wax was similar to that of the cotyledons. The esters are composed of monounsaturated long chain acids and alcohols.

 Title    and Chemistry and Morphology of Epicuticular Waxes from Various Organs of Jojoba (Simmondsia chinensis [Link] Schneider)  
 Abstract    The surface o f leaves and seed coats o f Jojoba is covered with sim ilar am ounts o f epicuticular waxes per surface area. The com position o f these waxes was analysed by chem ical methods, whereas their microscopic structures in situ were revealed by scanning electron m icroscopy. Differences in the chemical structure and com position o f the com plex m ixtures cause differences in the morphological appearance o f wax on the surface o f both organs. The predom inance o f saturated and long chain components in leaf wax results in a crystalline wax layer on this organ. In contrast, the seed coat carries a cover o f non-crystalline fluid consistency. The lower m elting point o f this wax mixture is caused by shorter chain and unsaturated com pounds predom inating on this organ.

 Title    Epicuticular Waxes of Seed Coats from Species of the Genus Cistus L. (Cistaceae)  
 Abstract    Epicuticular waxes were extracted with hexane from seed coats o f 16 species from the genus Cistus (Cistaceae) in amounts corresponding to an average o f 0.07% per dry weight. All cuticular waxes obtained from the various Cistus species consisted o f hydrocarbons, wax esters, triterpenol esters, aldehydes, primary alcohols and free fatty acids. These com pounds were present as homologues in changing patterns. In addition two unidentified acids and two unknown alcohols were found. Epicuticular waxes from seed coats differed qualitatively and quantitatively from those o f Cistus leaves and petals and confirmed the existence o f organ sp ecific com positions o f epicuticular waxes. The wax com ponents secreted in this com position result in a cover which in scanning electron microscopic pictures resembles a sm ooth layer o f solidified fluid lacking any crystalline structure.
