Entheogenerator said:but it smells very strongly of D-limonene. I really have no way of knowing how much of it is mescaline and how much of it is concentrated D-limonene residue, so if all else fails I may perform a mini-A/B on it using Xylene.
The d-limo smell will go away after some IPA and Acetone washes. Most probably you have some non-mesc alkaloid mixed with some orange oil left in your powder. Multiple times washed mesc still has a very faint earthy smell at least for me. I never managed to get the ultra white crystals you sometimes see in pictures. But more like a greyish off-white crystalline powder.
You'll notice that when you evaporate the wash solvent you'll be left with a waxy purplish pungent earthy/orangy smelling stuff consisting of the acetone soluble alkaloids and some fats which came over with the small amount of limo.
