Here: Mescaline quantification in live cacti using TLC.

See the attached PDF file, step 9). The actual tek is in the second half of the document.

The initial extraction is actually done in basified ethanol (since freebase mescaline is said to be more soluble in ethanol), then transferred to acidified water and then filtered.

I guess the water phase is added to remove water-insoluble impurities (there is quite a lot of them depicted).

So the benefit of using two solvents (EtOH, H20) is the opportunity to remove more impurities. I am not sure how that applies to DMT-containing plant material used by OP.
