Composition of the epicuticular and intracuticular wax layers on Kalanchoe daigremontiana (Hamet et Perr. de la Bathie) leaves

Cuticular waxes from both adaxial and abaxial surfaces of the leaves of Kalanchoe daigremontiana contained approximately equal amounts of triterpenoids and very long chain fatty acid derivatives. The triterpenoid fraction consisted of glutinol, friedelin, glutanol, glutinol acetate, germanicol and β-amyrin. The intracuticular wax layer contained higher percentages of most triterpenoids than the epicuticular wax. Friedelin showed the opposite distribution.
