yeah, acetone will extract everything, including bad stuff, which is why we dont see it used as an organic extraction solvent.
Usually the whole point of 'extracting' anything is to achieve a degree of selectivity in your solvent choice, acetone is about the king of non selective hydrocarbon solvents.
I never liked naptha as a solvent, it is a lazy solvent, but it's use as a de-fatting solvent in the extraction of mimosa (dmt) makes use of these qualities, but you have two hydrocarbon solvents.....usually any two hydrocarbons are miscible in each other to whatever degree.
The only way an extraction works at all is that what you're extracting is soluble while the rest is insoluble. If your solvents dissolve in each other, (a property chemically known as 'miscibility'), then you can't extract anything....you must have two layers so garbage can be left behind in one of them.
Do a test and mix naptha and acetone in a beaker or jar, and see if they dissolve in each other...this gives you the answer to your question.
To my understanding, the two superior ways ro extract these goodies are;
Ice-o-lator, which I have heard great things about,
and
butane, which is usually done thru a pipe, and is an explosion hazard.
good luck
