You could filter it thoroughly to remove non active solid particles. Then add a base such as lye (can you find it? If not we find alternatives but lye is good option), and some stuff will crash out, forming some solids in the bottom.
You could then use limonene (pm me for brazil source of limonene) which would dissolve DMT and other possible trace tryptamines, but would leave undissolved the harmalas. After you do 3x pulls with limonene, you proceed to retrieve your alkaloids from limonene such as following BLAB tek, but then you will go back to the base soup which should still have your undissolved harmalas on the bottom. Then you filter that (probably pain in the ass but hey, you asked for it
), and on top of the filter will stay your harmalas plus some impurities.
Then to clean the harmalas you check wiki harmala extraction guide, it will basically be dissolving it again in vinegar and reprecipitating by adding base again, repeating till you have cleaner product.
This is all theory though, a few odd things could happen, like for example harmalas might not precipitate nicely, but at least your DMT you should be able to recover properly by basing and adding solvent.
If for some reason this plan doesnt sound good, let us know why and we can work an alternative plan. And let us know if it works out or not, if you do try
