Hey Trampyman, welcome to the nexus.
It's not against the forum rules to do a not so small extraction. It is against the rules to do commercial scale extractions, which i personally feel is not very far away but not quite there yet with your 200g of bark. And it is against the rules to mention anything about buying or selling either bark or extracted alkaloids, so please don't do that again.
IMO it can make sense to want to extract a stash that lasts a year or two. However, that's once you know what you're doing.
When you try an extraction the first time, especially when you don't fully understand every aspect of it (like which solvents are good to use), you should always go small. Like 20-50g of bark - an amount that's easy to handle, gives a respectable amount of product in case of success (half a gram is like 20 smoalks!), but isn't a great loss if things go wrong.
Remember that the trees are living beings, and we should treat their barks with respect and care. The spice is invaluable.
In your case, if you already did the pulls with that solvent, my guess is that it did pull the dmt, but it didn't precipitate during the freeze because some constituents of your solvent don't have that nice temperature dependent solubility gradient for DMT.
If my guess is true, (at least part of) the DMT is no longer in the basic soup, but trapped in the solvent. So you'd basically have one or two options to retrieve that:
- if you have more of the same solvent, you can do an evap test with a bit of fresh solvent. If it evaps without leaving any traces, simply evaporating all of your DMT ladden solvent is a possibility.
- if you can't do an evap test or if the evap isn't clean, you'll have to backsalt. For example you could liquid-liquid extract from your solvent using acidic water (eg. dilute acetic or citric acid), converting the DMT back to a salt in the process. You could then base again, pull with a good solvent such as n-heptane this time, and go for freeze precipitation again.
Until you're sure, don't toss anything. My guess might be wrong, your solvent incapable of holding DMT, and everything still in the soup. Or maybe my guess is right but you've done only one pull from the soup, and there's DMT both in your solvent and still in the soup.
Ideally, you'll see this as an opportunity to learn and practice some useful techniques, follow a methodical approach to save your DMT wherever it is
