afaik gramine is basically insoluble in naphtha at room temp. (idk about other temps, or hordeneine)dmtmd said:In terms of plant toxic removal Swims main targets of removal are gramine and hordenine. Swims having trouble finding a good recrystallizing agent that dissolves dmt at high temperature and gramine at low. Swim knows lemonine is a good room temperature solvent to get rid of gramine, but not for recrystallizing.
