As many of you know, a much larger yield (and of full-spectrum alkaloids) can be obtained via using xylene as the extraction solvent in a STB extraction. (I prefer ether or chloroform, which are both easily available here in the netherlands thankfully.) I've found xylene to extract the majority of active alkaloids in just two or three pulls. However, freeze precipitation is not possible with this solvent as the DMT is much too soluble.
Evaporation can take weeks and makes your apartment smell like a marker factory.
A viable solution to this is to salt out the alkaloids using fumaric acid saturated acetone. However, i have found another method to retrieve the alkaloids very quickly without requiring access to a specific acid.

Once you have separated your xylene from the basified mimosa soup, wash the solvent two or three times using 100-200ml of methanol. You will notice color leaving the xylene and the methanol becoming dark. Now, you could simply evaporate the methanol to leave a crude and oily full spectrum extract and clean it by recrystallisation. I prefer acidifying the methanol slightly (just a few drops of 10% HCl is sufficient).
The dmt crashes out instantly in spectacular fashion and can then be dried.

I then take the extract, dissolve in a small amount of water and basify, then extract with ethyl ether to yield almost white crystals, only one or two recrystallisations away from looking like glass.

Very cool. You must add excess methanol since methanol is slightly soluble in xylene. Nice looking hcl crystals, I was always under the impression that dmt hcl formed an amorphous goo. Given the absense of water though it makes sense. Interesting report!

So you pull the alkaloids from the xylene with acidified methanol, seperate, and evaporate? Or you pull with plain methanol, seperate, then acidify?
