In such latest instances, the resin is mixed with pigments affecting its physical and chemical properties. A new procedure based on gas chromatography-mass spectrometry (GC/MS) has been applied, in this work, in combination with Fourier transform infrared spectroscopy (FTIR), with the aim of determining the changes undergone by di- and triterpenoid resins employed as components of binding media. The GC/MS method is based on the derivatisation of these resins using trimethylsilylimidazol. Characterization of the main components of the di- and triterpenoid fractions and their oxidised products, occurring in the diterpenoid resin colophony and a triterpenoid Mexical copal (Bursera cuneata (Schl) Engl.), has been achieved." .
