Read the thread I linked - that particular tek has been dissected many times, unfortunately, Shulgin got it wrong. Because psilocybin is always a charged compound, it's going to pull a lot of junk with it. I think analysis found that, when following Shulgin's tek, you were getting less than 50% purity. If all you want is just a solid thing you can eat, then it works fine, but when we talk about recrystalization, we're usually talking about a purification technique to yield very pure product.hermes111 said:Here this might be helpful.
As I said my own method isn't very useful for beginners, because if you don't do it right, you would be getting exactly the same result like when you just soak some shrooms in alcohol and evaporate that. Very impure & crude extract. You'd have to stay on top of it and separate the precipitate several times from the solvent at the right time to get different grades of product and have to pick the right one. As I said it gives crystals, but they're still contaminated with Polysaccharides.
To be honest I don't even do it myself anymore, not worth the effort to me, I like dry shrooms. The only benefit is that you can smoke the product, but only in low amounts, never managed to breakthrough, the complex sugars seem to get into the way somehow.
benzyme said:ethanol will not dissolve/separate any structural proteins from the alkaloid, the complexes readily precipitate out of anhydrous ethanol. charge-based separation is required to get rid of the "gunk", i.e. separation of a dilute acidic solution on a bed of cation exchange resin, and elute with dilute ammonia, while gradually altering the pH. keep in mind though, dephosphorylation may occur at pH > 9, and pH < 3. solvent partitioning is another option, this is done following a series of A/B extractions.
for TLC, the eluant is typically butanol:methanol: dilute ammonia 4:3:1.5. alternately, ethyl acetate may be substituted for the methanol, and acetic acid is substituted for the ammonia.
psilocybe alks aren't very stable as zwitterions, and have the tendency to bind anything electrostatically. anionic psilocin (which is what you'll get if you basify to pH 10-12, net charge of -1) is most stable as a salt complex, preferably with an acid having antioxidative properties, i.e. maleic, or tartaric acid. this complexation would ideally occur at pH 2-3.
