It never ceases to amaze me how such a simple procedure as basic everclear extraction rapidly turns into an overly-complex digression into basement psuedo-chemistry...
Put shrooms in everclear. Wait. Strain, evap, enjoy.
Notice the lack of vacuum pumps, potentially toxic chemicals, and a time consuming array of filtrations, dehypholyzations, and god knows what someone could do to a batch of shrooms for ? reason... ?
Even if you don't want to drink alcohol with your shrooms, you can evap it down to 5mls / gram easily, which is less alcohol than you'd get in your system after swishing with listerine.
As for the kind of alcohol to use, the higher the proof the better. Water may be more efficient in extracting all of the compounds from the shroom, as well as lower proof alcohols, but the whole point of alcohol extraction (for me) is that there isn't water involved (not enough, at least), so whatever makes your stomach and bowels do flips stays in the shroom, not in the extract.
Discussions on topics such as " Dephosphorylation of Psilocybin to Psilocin" will only muddy the waters for people who just want to make a good extract, which can be done with nothing more than a sackful of shrooms and a bottle of everclear - nothing else needed to make a top-notch product.
Some concepts are just too easy for those folks who revel in making life difficult, but each to his own I suppose.
