Ayahuasca, a psychoactive beverage traditionally used by indigenous Amazonian tribes for ritual and medicinal purposes, contains compounds such as N,N-dimethyltryptamine (DMT), β-Carbolines, and harmala alkaloids including harmine, tetrahydroharmine, and harmaline. The harmala alkaloids act as monoamine-oxidase inhibitors, enabling DMT's psychoactive and hallucinogenic effects on the central nervous system. Despite consumer advocacy, the metabolic and central nervous system effects remain incompletely understood. This paper critically reviews toxicological aspects and analytical methods for detecting these compounds in biological and non-biological specimens, emphasizing instrumental developments and sample preparation approaches.

Ayahuasca, a beverage used in shamanic ceremonies and increasingly recreationally, contains beta-carboline alkaloids and N,N-dimethyltryptamine, which have hallucinogenic effects. This work examined the cytotoxic effects of these compounds and of five different teas (Banisteriopsis caapi, Psychotria viridis, Peganum harmala, Mimosa tenuiflora, and a commercial preparation) on dopaminergic immortalized cell lines. The extracts were characterized chromatography, and their effects on cell viability and total protein levels were analyzed in N27 dopaminergic neurons. This is the first study of ayahuasca tea's cytotoxicity on neurological dopaminergic cells. Results showed that both cell viability and protein contents decreased when cells were exposed to the individual compounds, teas, and mixtures based on traditional ayahuasca beverages.

Ayahuasca's potential as a therapeutic agent is underscored by its complex chemistry. In a study involving 150 participants, significant levels of harmine and harmaline were identified using gas chromatography–mass spectrometry and solid-phase extraction methods. These compounds, derived from peganum harmala, highlight ayahuasca's pharmacological properties. The findings suggest that traditional medicine practices may offer valuable insights into the therapeutic use of psychedelics, including implications for cannabis and cannabinoid research and advancements in forensic toxicology and drug analysis.
