Subject: TEONANACATL 1995 PCYAO, part 3: analytical data

  • Samples of Psilocybe cyanescens Astoria Ossip [new: P. azurescens] (from outdoor natural culture) and also Psilocybe cubensis (cultivated on straw, indoors) and Psilocybe semilanceata (collected from their natural habitat) were found to contain the following amounts (in % of dry weight) of alkaloids:

                               Psilocybin  Psilocin       "total" (1)
    
    PCY-AO-94, caps               0.7       0.4            1.3
    PCY-AO-94, stems              0.8       0.2            1.1
    PCY-AO-93                     1.0       0.4            1.6
    PCY-AO-91                     0.9       0.1            1.0
    
    Ps.Cub.-91                    0.4       0.1            0.5
    
    Ps.S.-93, grade A+            1.1        -    (2)      1.2
    
    
    These results are in very good agreement with the estimated relative potencies published in part 1.

    All samples had been dried below 30 xC, and stored refrigerated in airtight containers. Analyses were performed very recently by Dr. Jochen Gartz - certainly "the" European expert in this field - at the University of Leipzig. An American edition of Dr. Gartz's book "Narrenschwaemme", which contains a lot of information not to be found anywhere else, should be available this spring (3).

    NOTES

    (1) After ingestion, psilocybin is hydrolized to psilocin pretty rapidly and completely. 100 mg of psilocybin (C12H17N2O4P, MW=284.3) are equivalent to 72 mg of psilocin (C12H16N2O, MW= 204.3), or - in oth"total" here refers to the (thus calculated, and rounded) equivalent of psilocybin.

    (2) Ps. semilanceata also contained 0.2 % baeocystin (others only traces). Baeocystin has effects on humans very similar to those of psiloc(yb)in, but is weaker (per weight) (J.Gartz, pers. comm.)
