Is all that really necessary? Albert Hofmann did the procedure in that order and he didn't do any of that. I asked on Bluelight how to adapt what Hofmann did and was told to just mix up the tar into naptha and then run it through a coffee filter and that defatted alkaloids would be left sitting on the filter (and the filter itself is one's near-end product and it can be infused in a liquid for the purpose of evaporation or just infused in a liquid and then drunk.)
We started our extraction studies with
Rivea corymbosa. Since we knew nothing of the chemical nature and sensitivity of the active principles, only neutral solvents were used and all extracts were evaporated carefully at low temperature. The finely powdered seeds were extracted with methanol, and the evaporated methanol extracts were defatted with petroleum ether. The defatted residue was tested for various kinds of alkaloids, especially for indolic compounds, since the indole structure was known to occur in psychotomimetic agents. Indeed, when paper chromatograms of this
Rivea extract were developed by spraying with a benzene solution of p-dimethylamino benzaldehyde and subsequently treated with hydrochloric acid gas, violet-blue spots appeared, indicating the presence of indolic compounds. In order to assess whether this indole fraction actually represented the active principle, we collected some milligrams of this fraction from a great number of paper chromatograms and my laboratory assistant H. Tscherter and I tested it on ourselves. After my experience with LSD, I have become cautious: we started by taking doses as small as 0.1 mg., gradually increasing the dosage. With 2 mg. of this crude indole fraction we got clear-cut psychic effects: a dream-like state resulted with drowsiness and alterations in the perception of objects and colors. This showed that the indole fraction of the
Rivea extract contained the psychic active principles.
