Resumo
Psychotria viridis is one of the species that produces N,N-dimethyltryptamine. Its decoction
together with other species, such as Banisteriopsis caapi, produces ayahuasca, a beverage used for
ritualistic and medicinal purposes. The goal of this study was to understand how environmental
factors and cultivation methods influenced the content of N,N-dimethyltryptamine in P. viridis.
Over all four seasons, leaf samples were collected from 25 different locations in 14 Brazilian
states, and Federal District. Environmental parameters, micro and macronutrients, plant
characteristics, information on farming methods were correlated with N,N-dimethyltryptamine
content, determined by gas chromatography coupled to mass spectrometry (GC-MS). Greatest
effects on the N,N-dimethyltryptamine amount were associated with seasonality, altitude, latitude
and biome type. A positive correlation between N and Mg content and N,N-dimethyltryptamine
levels was statistically established. By regression analysis, the adequate foliar nutrient levels that
would result in the concentration of N,N-dimethyltryptamine in cultivated plants similar to that
of Amazonian P. viridis were equated.
