The usefulness of Fourier transform infrared (FT-IR) spectroscopy for ident
ifying functional groups ascribed to different biopolymers present in isola
ted plant cuticles is described and their relationships to the structure of
the plant cuticle are discussed. For this purpose the isolated cuticle fro
m Clivia miniata leaf has been investigated. The ability of the FT-IR techn
ique to follow the isolation of the main components of isolated plant cutic
les is also discussed.
