I was able to travel out onto the ocean into international waters where I worked on improving on this.
I am no chemist by any means. I will be writing a newer tek shortly. Here's another pic...sorry about the lighting
Acacias I have been reading about in my research contain a wide variety of things. Shulgin said something about 2 acacias in Texas containing alkaloids which were only thought to be made by man in the lab. One was amphetamine, I forget the other one off hand. Most contain tryptamine related alkaloids while others contain trpytamines and beta-carbolines. A very interesting species indeed. With more than 2,500 known species of acacia and more and more species of plants and fungi being found every year with tryptamines in them. The question shouldn't be, "Where is DMT found?", but rather "Where isn't it found?". I also heard reports of some species of acacias containing cyanide. I have yet to find a refrense for this but then again who knows.
As far as I know the best source for dimethyltryptamine is from the rootbark of the mimosa hostilis.
Another tip would be not to shake. Slow stirring will cause the emulsion layers to form in seconds rather than hours or days.
Use distillation and a vacum if possible. Im sure this only helps more. When raising the pH, the solution will turn from red to grey. Grey is bad, keep adding solution till it goes black. The faster the better I've heard.
More later...
Hope that helps...
