Partitioning? What do you mean by that? When it's an insoluble solid phase versus a liquid phase, we don't really talk about partitioning. DMT is exceptionally soluble in aqueous ethanol; rinsing the precipitated calcium tannin a couple of times with a little more vodka recovers effectively all the soluble alkaloids. The rinsing makes up for whatever mechanical holdup of dissolved DMT there may have been.
