The authors developed and validated a simple, low‑cost SPE–LC method with UV diode‑array detection for quantifying N,N‑dimethyltryptamine, tryptamine and β‑carbolines in ayahuasca, showing good linearity (r>0.9902), excellent repeatability (RSD<0.8%) and an LOD of 0.12 mg/L. Applied to 20 samples from a Fortaleza religious group's brew, the method found target compound concentrations ranging widely from 0.3 to 36.7 g/L.
