Abstract: A capillary zone electrophoretic (CZE) method was developed for the rapid determination of psilocybin in Psilocybe sentilanceata. Following a simple two step extraction with 3.0+2.0 ml methanol, the hallucinogenic compound was effectively separated from matrix components by CZE utilizing a 10 mM borate-phosphate running buffer adjusted to pH 11.5. The identity of psilocybin was confirmed by migration time information and by UV spectra, while quantitation was accomplished utilizing barbital as internal standard. The calibration curve for psilocybin was linear within 0.01-1 mg/ml, while intra-day and inter-day variations of quantitative data were 0.5 and 2.5% R.S.D., respectively. In addition to psilocybin, the method was also suitable for the determination of the structurally related compound baeocystin. (C) 1997 Elsevier Science B.V.

great work, as usual. I need to renew my comments, but hey...

Wouldn't this fit better in Tryptamine Chemistry?

Yes, sorry. I get very confused with the chemistry stuff
