Samples dried by direct solar heat also showed instability for DMT and ß-carbolinic compounds concentration

The highest DMT concentration and greater stability between THH/HRM ration found in Ayahuasca made with plants dried at 43 and 45°C, for P. viridis leaves and B.caapi stems,

Rainfall and water capacity of the soil showed to have straight relationship with the alkaloid contents of DMT, HRL, HRM, and THH in Ayahuasca. In the winter period, with higher rainfall, the alkaloids concentration in Ayahuasca prepared with plants from the TF ecosystem increases. Nevertheless, plants from CAMP seemed more adapted to water stress and the tea made with plants from this ecosystem had lower seasonal variation on the alkaloid’s concentration.
