The chemistry of American and African amber, copal, and resin from the genus Hymenaea

The comparison of the chemical composition of fossilized amber, copal, and resin is important for determining the botanic origin and original chemical composition of fossilized amber and copal, and for understanding the ecologic role of resin. Here we use solid phase microextraction–gas chromatography–mass spectrometry (SPME–GC–MS) to investigate the volatile and semi-volatile composition of amber, copal and resin from Africa and the Americas,...
