Under opening comments (p 3)

  Banisteriopsis was finally observed being used in the preparation of a traditional snuff. Robin Rodd witnessed and bioassayed highly potent snuff prepared from Anadenanthera peregrina seeds pounded to a paste with the fresh shoots of Banisteriopsis caapi before being kneaded with ash and heated to dryness. (Rodd 2002)

Under psilocybin (p. 86):

  In a controlled double-blind experiment, researchers reported that 61% of participants given a strong dose of psilocybin (as 30 milligrams of psilocybin per 70 kilograms of body weight) had a "full mystical experience," as measured on established psychological scales. Two-thirds of the 36 participants rated the experience as either the single most meaningful experience or among top five most meaningful experiences of their lives. 79% of the participants reported a moderate or greatly increased sense of well-being or life satisfaction two months after taking the drug. None had previously used any hallucinogen and over half were active in church or another spiritual community. Griffiths et al. 2006

Under bufotenine (p 107):

   Acacia obtusifolia has apparently been reported to contain variable amounts of bufotenine in the resin extracted from the stembark. In the four samples where it was reportedly observed, it was as a minor component that appeared to be highest in a winter extract compared to the faint traces in a summer extracts (using gc-ms.) (Trout 2005)

  This appears to be the first report of bufotenine in an Acacia species. It was not corroborated by a second worker's gc-ms but this was thought to be possibly due to lack of appropriate column equilibration. The presence of bufotenine was more recently confirmed in 2005 by Ott using tlc with known reference material according to a friend who was visiting him when this occurred. (Anonymous in personal communication)

  Betacarboline(s) are thought have been observed in the root bark (suggested by fluorescence and bioassay results in summer of 2003) but there was no attempt at identification.

  One stem bark alkaloid was thought to possibly be 1,2-dimethyl-1,2,3,4-tetrahydro-β-carboline based on the second worker's gc-ms mentioned above but the identity was never actually established. (Trout 2005)

  Earlier hplc-ms work by Mulga appears to have also observed a betacarboline in the stem bark but it was not identified.
  Mulga did not observe bufotenine. (Mulga 2005)

  In all cases mentioned above, DMT was the major alkaloid.
