Many members here at the nexus have asked me several times to write up this back extraction technique. This "step" can be most useful when working with fatty plant materials, or "clorophyll heavy" materials such as chaliponga, chacruna, large batches of MHRB, and especially Phalaris extractions.
Regardless of what type of material you are extracting this can be an invaluable step to obtaining pure end products. This is a one step defat , meaning that every pull of solvent is mixed with an appropriate portion of heavily acidic water, (less alk's = less water) mixed for a short time, and the solvent either discarded or recycled.
During the mixing phase of this step the alkaloids attach to whatever acid was used to acidify the water, forming a salt. The alkaloids then become insoluble in the np solvent that was added and then migrates to the water layer. This leaves behind ALL of the fats and oils and ANY non water soluble contaminants that may be present in the solvent to be removed.
The water is then either evapped to yeild a salt or is re-basified and extracted oce again with fresh clean solvent to leave as a finished product beautiful snow white crystals (aside from any other colored alkaloids that may be pulled by varying solvents.)
The real beauty of using this step is that everything can pretty much be straight to based.. and the solvent added shortly after or even at the same time and sat aside for x amount of time, or heated for x amount of time. Solvent is removed per normal then simply added to some heavily acidified water. The solvent is then , after stirring, discarded and the solution re-basified and clean solvent added.
This completely removes the need for traditional , solvent wasting defats. It also eliminates the need for an acidic boil at the start of an extraction, making it obsolete, since a boil (or rather a steep) in basic solution will better release the alkaloids and break down the plant material better than that of an acidic one.
This is also useful when performing several pound extractions of MHRB as it allows for ALL of the crystals to come out clean and spotless as opposed to the first few pulls being nice and white and subsequent pulls yellow or oily.
Overall this is an exceptional method of deffatting any extraction. This tek should completely eliminate the difficulty of extracting those fatty/ green materials.
Peace and Godspeed!
