All plants that contain DMT must also contain DMT N-Oxide unless they are somehow either shielded entirely from oxygen or they contain large amounts of antioxidants like vitamin C.
DMT oxidizes quite easily. The plant sources of DMT all create oxygen as part of their life cycle. The plant’s leaves are the primary site responsible for photosynthesis. The process of photosynthesis generates oxygen as a waste product. That’s why leaves usually contain large amounts of DMT N-Oxide. So when extracting from leaves such as Diplotperys and Chancruna, solvents like naphtha and heptane are not recommended because they cannot extract DMT N-Oxide. Solvents like DCM and ether are better choices for extraction from leaves. This rule applies almost universally to all alkaloids extracted from leaves because the N-Oxides of nearly every alkaloid, not just DMT, are insoluble in naphtha and heptane.
Root bark is not responsible for photosynthesis, and it is not fully exposed to open air, but some oxygen is present in the soil that surrounds the root bark, so some DMT N-Oxide does form in root bark. The inner bark should have less DMT N-Oxide than the outer bark has before it is harvested. But once it’s harvested much of it starts oxidizing into DMT N-Oxide on the surfaces of the bark exposed to open air.
I guarantee that all the plant sources of DMT available on the market do contain DMT N-Oxide. Unless the plant material is stored away from oxygen or kept in an antioxidant solution, then it will contain DMT N-Oxide. All it takes is a few minutes in warm temperature with available oxygen and DMT N-Oxide starts forming from DMT.
One reason why many sources do not show DMT N-Oxide content in plant material is because nearly all tests detect DMT N-Oxide as DMT.
You can easily verify that Mimosa has DMT N-Oxide. First, defat your acidic solution 10 times with DCM, and then 10 times with naphtha to ensure it’s completely defated. Then basify and exhaustively extract your basified solution 10 times with naphtha. Then extract only 3 times with DCM. The DCM always pulls out some DMT N-Oxide. When it dries it forms a yellowish goo that is quite active. It feels very similar to DMT, but is a little mellower. Test it, and it shows up in most tests as DMT, but it’s obviously not DMT because it’s insoluble in naphtha.
NOTE: According to SWIM, DCM is the best solvent for extracting DMT N-Oxide. DMT N-Oxide is insoluble in naphtha, xylene, and heptane. It’s poorly soluble in ether and chloroform, but more soluble in DCM, and extremely soluble in water. So unless you’re using DCM, ether, or chloroform, you’re not extracting DMT N-Oxide.
You may remember me as 69Ron. I was suspended years ago for selling bunk products under false pretenses. I try to sneak back from time to time under different names, but unfortunately, the moderators of the DMT-Nexus are infinitely smarter than I am.
If you see me at the waterpark, please say hello. I'll be the delusional 50 something in the American flag Speedo, oiling up his monster guns while responding to imaginary requests for selfies from invisible teenage girls.
