Its not possible to identify from a picture, all we see is yellow. I would guess just dmt + plant oils/impurities. Jimjam is anyways mostly plant dmt + oils/fatty acids, according to burn's analysis. The only other interesting possibly active alkaloid is 2-MTHBC which nobody knows if its active, but its only in very very small quantities and unlikely will be active at such minute doses. But even if it was active, according to it's xlogp it is most likely (or for sure, but I dont know for certain) NOT soluble in naphtha, so you wouldnt get it in your product.
There may be some n-oxide there formed during the reduction, but to be honest when people claim n-oxide its just pure guess, there hasnt been AFAIK chemical analysis to support those guesses. I would think there isnt any or very little there, because naphtha shouldnt pull it in the first place.
Even using hydrogen peroxide to purposely oxidize dmt might just oxidize a part of it and still leave a significant quantity of dmt (as bufoman seems to think). Also considering dmt n-oxide should be a full oil, even if there was some in your product, it will be a small quantity since one can see its quite "solid".
Personally whatever it is, I would redissolve in ethanol/IPA/acetone and re-evap again to get rid of solvent traces.
