N , N ‐dimethyltryptamine (DMT) is a widely distributed plant alkaloid that displays partial agonist activity at the 5‐HT 2A receptor and induces intense psychedelic effects in humans when administered parenterally. However, self‐administration studies have reported a total lack of activity following oral intake. This is thought to be due to extensive degradation by monoamine oxidase (MAO)....
Ayahuasca denotes an Amazonian psychotropic plant tea obtained from Banisteriopsis caapi, which contains beta-carboline (b-carboline) alkaloids, chiefly harmine, harmaline and tetrahydroharmine. The tea usually incorporates the leaves of Psychotria viridis, which are rich in N,N-dimethyltryptamine (DMT), a psychoactive 5-HT2A agonist. The beta-carbolines reversibly inhibit monoamine-oxidase...
Ayahuasca is an Amazonian psychotropic plant tea obtained from Banisteriopsis caapi , which contains β ‐carboline alkaloids, chiefly harmine, harmaline and tetrahydroharmine. The tea usually incorporates the leaves of Psychotria viridis or Diplopterys cabrerana , which are rich in N , N ‐dimethyltryptamine (DMT), a psychedelic 5‐HT 2A/1A/2C agonist. The β ‐carbolines reversibly inhibit...
Three indole alkaloids that possess differing degrees of psychotropic/psychedelic activity have been reported as endogenous substances in humans; N,N-dimethyltryptamine (DMT), 5-hydroxy-DMT (bufotenine, HDMT), and 5-methoxy-DMT (MDMT). We have undertaken a critical review of 69 published studies reporting the detection or detection and quantitation of these compounds in human body fluids. In...
Ayahuasca is an Amazonian psychotropic plant tea combining the 5-HT2A agonist N,N-dimethyltryptamine (DMT) and monoamine oxidase-inhibiting β-carboline alkaloids that render DMT orally active. The tea, obtained from Banisteriopsis caapi and Psychotria viridis, has traditionally been used for religious, ritual, and medicinal purposes by the indigenous peoples of the region. More recently, the...
A direct injection/liquid chromatography-electrospray ionization-tandem mass spectrometry procedure has been developed for the simultaneous quantitation of 11 compounds potentially found in the increasingly popular Amazonian botanical medicine and religious sacrament ayahuasca. The method utilizes a deuterated internal standard for quantitation and affords rapid detection of the alkaloids by a...
