Chemistry of leaf waxes in relation to wetting

Journal of the Science of Food and Agriculture, 1969
AbstractThe hydrophobic property of waxes depends upon their chemical constitution and almost certainly upon the orientation of molecules of their constituents. Contact angles of the most important classes of constituent range from 94° to 109°. No class of constituent is very water‐repellent; alkenes are the most hydrophobic but esters, ketones and ...

Leaf wax constituents of some myrtaceous species

Phytochemistry, 1983
Abstract Eucalyptin and 8-desmethyleucalyptin have been isolated from the leaf wax coatings of several species of Eucalyptus, from Syncarpia glomulifera, Lophostemon confertus and an Angophora hybrid indicating that C-methylated flavones may be fairly distinctive of the family Myrtaceae.

Inheritance of Leaf Epicuticular Wax Content in Rice

Crop Science, 1992
Leaf epicuticular wax (EW) is a trait related to drought resistance. Epicuticular wax content is low in rice (Oryza sativa L.) relative to other crops, but great differences among rice cultivars have been observed, as great as 100%. Traditional drought‐resistant upland rices have relatively higher EW content than modern irrigated lowland rices.

Changes in the composition of coffee leaf wax with development

Phytochemistry, 1975
Abstract Coffee leaf wax contains alkanes, free primary alcohols and free acids, together with unidentified substances. The relative amounts of each fraction varied with age: alkanes from 22–35% alcohols from 28-25%, and free acids from 22-14%. The major homologues of the alkane fraction were C 29 and C 31 , of the alcohol fraction C 30 and C 32 ...

Secondary alcohols from Fragaria leaf waxes

Phytochemistry, 1979
Abstract The secondary alcohols isolated from Fragaria leaf waxes and characterised by GC-MS have been shown to be a mixture of isomers of hentriacontanol with the hydroxy substituent on carbons 9, 10, 11 and 12, and of tritriacontanol with the OH group in the 10, 11, 12, 13 and 14 positions, respectively.
