- O.K., for all the poor souls who had to ingest those horrible
- seeds, here is an extraction than I think anyone on this newsgroup can
- do in their kitchen without blowing themselves up.

- ISOLATION OF HARMINE AND HARMALINE
-
- "The crushed seeds of Peganum Harmala are covered with three times
- their weight of water containing 30 g of acetic acid per liter of
- water [white vinegar is about 50g / l or 5 %]. The seeds swell as they
- absorb the liquid and form a thick dough which is pressed after 2-3
- days. The pressed seeds are once more treated as above with twice
- their weight of dilute acetic acid and, after maceration, the liquid is
- again pressed out. To the combined liquors, sodium chloride [that's
- table salt, man] (100g. / liter of liquid) is added to transform the
- acetates of harmine and harmaline into the hydrochlorides which are
- insoluble in cold sodium chloride solutions and are precipitated
- during cooling. The supernatant liquid is siphoned off, the
- crystalline residue filtered with suction and redissolved in hot
- water. Addition of sodium chloride to the filtered solution causes the
- precipitation of the hydrochlorides as a crystalline mush and this
- process is repeated until the hydrochlorides have acquired a yellow
- color (for the purposes of this newsgroup, once is enough). The final
- product is then recovered by filtration."
-
- The paper then goes on to describe the separation of harmine from
- harmaline, but this procedure is slightly more complicated and not
- necessary for most purposes.

- P.S. While this procedure is legal in the U.S. (where harmine and
- harmaline are currently unscheduled), it is illegal in Canada where
- harmine and harmaline are Schedule I.

- These are extremely potent alkaloids. Misuse of them can result in
- serious, even fatal, consequences. Read the FAQ about MAO inhibitors.
