Introduction Galloylquinic acid derivatives and flavonoids are the main phenolic metabolites found in Copaifera langsdorffii leaves (Leguminosae, Detarioideae), a medicinal plant with potential therapeutic application in the treatment of kidney stones. The factors that affect metabolite production in this plant species are not well understood but may include environmental and genetic factors. Objective To quantify the variation in metabolite production over a 12-month period for 10 groups of C. langsdorffii cultivated under the same environmental conditions. Methods Copaifera langsdorffii seeds were collected from 10 different regions in southeast, Brazil and grown in the same field. HPLC-UV was used to quantify nine galloylquinic acid derivatives and two flavonoids in leaf samples from mature trees. Climate data for humidity, radiation, precipitation and temperature were provided by the National Institute of Meteorology, Brazil. Multivariate analyses were performed to correlate chemical and environmental variables. Results The overall effect of environmental factors on the production of phenolic metabolites was uniform among C. langsdorffii groups. Chemical variation between groups was present, but small, and probably due to differences in their genetics and physiology. Seasonal changes influenced the production of the major phenolic metabolites, with increases in temperature and radiation levels favouring metabolite production. Conclusion 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. (AU)
