Abstract A total of 32 Banisteriopsis caapi samples and 36 samples of Psychotria viridis were carefully collected from different plants on the same day from 22 sites throughout Brazil for phytochemical analyses. A broad range in alkaloid distribution was observed in both sample sets. All B. caapi samples had detectable amounts of harmine, harmaline and tetrahydroharmine (THH), while some samples of P. viridis had little or no detectable levels of N,N-dimethyltryptamine (DMT). Leaves of P… Expand
Various alkaloid profiles in decoctions of Banisteriopsis caapi.
TLDR
The alkaloid composition of one decoctions of Banisteriopsis caapi did not change significantly after standing at room temperature for 80 days, but the initial acidic pH was neutralized by natural fermentation after 50 days. Expand
Various Alkaloid Profiles in Decoctions of Banisteriopsis Caapi
TLDR
The alkaloid composition of one decoctions of Banisteriopsis caapi did not change significantly after standing at room temperature for 80 days, but the initial acidic pH was neutralized by natural fermentation after 50 days. Expand
Biodiversity of β-Carboline Profile of Banisteriopsis caapi and Ayahuasca, a Plant and a Brew with Neuropharmacological Potential
TLDR
This is the largest study conducted with Malpighiaceae samples and showed a large variability in the main β-carbolines present in B. caapi and ayahuasca, and confirmed that harmine is reduced to harmaline and to THH during the brew preparation. Expand
Chemical Composition of Traditional and Analog Ayahuasca
TLDR
Concentrations of the main bio- and psychoactive components of ayahuasca used in different locations and traditions are determined and awareness about the constituents of the brew and ethical self-regulation among practitioners ofAyahuasca ceremonies are recommended. Expand
Toxicological Aspects and Determination of the Main Components of Ayahuasca: A Critical Review
TLDR
This paper will perform a comprehensive and critical review on the analytical methods available for their determination in biological and non-biological specimens, with special focus on instrumental developments and sample preparation approaches. Expand
Ayahuasca: Uses, Phytochemical and Biological Activities
TLDR
Traditional ayahuasca beverage is generating pharmacological, commercial and spiritual interest among the scientific community, government people, and different populations worldwide. Expand
Vegetative anatomy, morphology and histochemistry of three species of Malpighiaceae used in analogues of the Amazonian psychoactive beverage Ayahuasca
TLDR
Histochemical analyses revealed the presence of important compounds of potential pharmacological use: alkaloids, saponins, essential oils, lipids, pectin, tannins and general phenolic compounds, mostly in parenchymatous tissues in the bark and lesser in the wood. Expand
LC-MS/MS quantitative determination of Tetrapterys mucronata alkaloids, a plant occasionally used in ayahuasca preparation.
TLDR
The consumption of this plant as an ingredient in ayahuasca preparations may present a risk to consumers, and the HPLC-ESI/MS/MS quantitation revealed significant alkaloid levels, in particular for bufotenine and 5-methoxy-bufotenines. Expand
Composition, standardization and chemical profiling of Banisteriopsis caapi, a plant for the treatment of neurodegenerative disorders relevant to Parkinson's disease.
TLDR
The correlation between potency of MAO inhibition and antioxidant activity with the content of the main active constituents of the aqueous Banisteriopsis caapi extracts and standardized compositions was established and was supported by the results obtained. Expand
Neuroprotective potential of Ayahuasca and untargeted metabolomics analyses: Applicability to Parkinson's disease.
TLDR
The results demonstrate that Ayahuasca and its base plants have potential applicability for PD treatment and the possibility to prevent its progression differently from current drugs to treat PD. Expand

Chemical and Pharmacological Evaluation of Banistereopsis argenteaSpring ex Juss
TLDR
The total alkaloids from the leaves have shown three main pharmacological actions: nonspecific spasmolytic action against acetylcholine-, histamine-, and serotonin-induced spasm; histamine release-mediated depressor response; and pronounced behavioral effects. Expand
Quantitation of N,N-dimethyltryptamine and harmala alkaloids in human plasma after oral dosing with ayahuasca.
TLDR
The one-step extraction method for DMT and the protein precipitation method for the three harmala alkaloid afford rapid, sensitive, and quantitative analyses of these alkaloids with minimal analyte loss. Expand
Diurnal fluctuations of the alkaloid concentration in latex of poppy Papaver somniferum is due to day–night fluctuations of the latex water content
TLDR
It is concluded that the observed diurnal fluctuations in the concentration of the major alkaloids are not reflections of enzymatic processes but the result of water transport between the laticifers and the surrounding vascular tissue. Expand
Monoamine oxidase inhibitors in South American hallucinogenic plants: tryptamine and beta-carboline constituents of ayahuasca.
TLDR
The levels of DMT and beta-carbolines found in the ayahuasca samples examined in the present study were an order of magnitude greater than the levels reported in a previous study, which indicated that their effects in combination are additive, rather than synergistic or antagonistic. Expand
