A gas chromatographic method was developed to simultaneously measure the main active alkaloids in ayahuasca preparations: N,N-dimethyltryptamine from Psychotria viridis and the β-carbolines harmine, harmaline, and tetrahydroharmine from Banisteriopsis caapi. Alkaloids were extracted using solid phase extraction and detected with a nitrogen/phosphorous detector. The method achieved a lower limit of quantification of 0.02 mg/mL for all analytes, with linear calibration curves from 0.02 to 4.0 mg/mL and precision below 10% relative standard deviation. This validated method can help estimate administered doses in animals and humans for future pharmacological and toxicological studies.
Lysergic acid diethylamide (LSD) significantly alters biochemistry, with 93% of participants experiencing enhanced mood and perception. In a sample of 150 individuals, biochemical analysis revealed that LSD interacts with cytochrome P450 enzymes, impacting metabolic pathways related to tryptophan, a key player in brain disorders. The study also identified quinoline as a primary metabolite, while catalase and myeloperoxidase activities were influenced by the drug. These findings highlight the intricate chemistry of psychedelics and their potential therapeutic applications in mental health.
