Hi there, sorry - long time no post and therefore no new news.

Now I included the NMR-Spectra of Spice with the maximum purity what you may get directly out of the A/B-TEK with NO further purification step.

This means:

> Pulling with Naphtha made of Hexane + PENTANE (Boiling Point 40 - 60 °C instead of 60 - 80 °C)

> Washing the Naphtha with NaCl-enriched water

> Freeze-precipitating it

This yielded the sample that was investigated by NMR. Again all other signals and Spice-only Signals were used to calculate the percentage of purity, what could be received by the method listed above and with NO RE-X.

And it is astonishing: 99,988 % insane purity level

This means that with this method it is totally unneeded to re-x, even if you want 99 % + purity (given the prequisite that the product is of constant quality).

That was really unexpected I must say!

Also and maybe even more exciting: the perfect pure Spectrum also shows that *strange peak* at ~ 8.3 ppm and therefore it 100 %ly belongs to DMT itself, more precisely it is surely that NH-Proton labeled as #5 in the prediction as we were presuming.

This is nice to know, because then this signal is NOT an impurity anymore and all those other samples are of much higher purity. I already corrected all pictures and all the text regarding it.

Therefore it is nice to hear that even the most unpure sample here is 80 %+. You really would not have expected this by judgment with the eye x)

Soon I will bring you the *Impurity-only* Sample I hope. I'm quite interested in that, I guess Mass Spectrometry will be very interesting here again, as we dont have any structures in mind what it could be and it may help to get a rough idea.
