If you did an A/B extraction that included a defat, then when the xylene cools, nearly pure bufotenine crystals will form. They are about 95% pure.
A xylene boil used for an acetone extract made from snuff will not produce a pure product. It should however get rid of all the toxins. It will be much more pure than the initial acetone extract.
Because you are using snuff, I would defat the prepared snuff using cold xylene before extracting with acetone. Freebase bufotenine is practically insoluble in room temperature xylene, so a defat with xylene prior to a xylene boil will dramatically clean up your final product. I would do 3 defats at least.
Here are a few things to remember about this xylene boil purification technique:
1 - DO NOT BOIL THE XYLENE ON A FIRE BURNER. That’s a good way to start a fire. Xylene is flammable. You need an electric hotplate.
2 - Boil your extract in the xylene for 5 minutes, and mix it a few times. Boiling any less than 5 minutes is ineffective. Pour the xylene off while boiling hot.
3 – Let the xylene cool down for at least 4 hours, then pour out the xylene leaving being your bufotenine stuck to the bottom and sides of the container. Re-use the xylene to get more bufotenine out of your extract.
Bufotenine is practically insoluble in xylene at room temperature (less than 0.03 g/100 ml), but very soluble in boiling xylene (over 1.5 g/100 ml). The ember toxins are insoluble in xylene at all temperatures. So by boiling in xylene you get rid of all the more polar toxins in the extract. If the extract was not defatted, the xylene boil will extract fats and oils as well as bufotenine. However, most of these oils and fats will stay in the xylene when it cools, while the bufotenine will precipitate out.
You may get pretty impure results the first time you do the xylene boil technique if you did not defat the material beforehand. If this is the case, defat your impure results with cold xylene. The impurities should dissolve in the xylene, the bufotenine will not. Discard the xylene and save the solids. Then repeat the xylene boil process with fresh xylene and you should get fairly pure bufotenine. The crystals should look white or slightly yellow or slightly tan, dry and brittle, not sticky at all. There should be no richly colored amber material and no dark brown or black material preset, if there is then repeat the xylene defat and repeat the xylene boil.
After pouring off the xylene, the crystals can be dried in an oven at 250 F.
...he is going to continue to dry the seeds..and once that is done he will boil with xylene..
