Quantitative analysis of phenolic metabolites in Copaifera langsdorffii leaves from plants of different geographic origins cultivated under the same environmental conditions.

When C. langsdorffii trees are cultivated in the same environment, the production of the major secondary metabolites found in their leaves is very similar quantitatively, varying based on geographic location of original population and seasonal changes. This favours the standardisation of plant raw material for the production of a phytomedicine.
