My neighbor's garden gnome has been attempting to perform this tek on some shredded caapi vine (of type/colour unknown), and has encountered the same problem in three different experiments....
The last run involved;
- boiling for 1hr, 150g of shredded vine in 750mL of water (enough to cover the material), which was added to it 75mL of white vinegar (4% acetic acid).
- strain off the solution, add a further 750mL of water and 75mL of vinegar, boil for further hour.
- repeat step two a further 2 times.
- boil-down relutant solution (approx. 1L), to 500mL.
The final solution did not quite have the thick, muddy texture and colour of ayahuasca. It seemed to be noticeably less concentrated than the solution pictured in this tek.
The addition of a 10% (wt./wt.) solution of NaOH caused the rapid precipitation of dark material, leaving a clear, ruby solution (as described in this tek - very similar to the photos).
This solution was decanted off after settling. However, even after several hours of standing, the solution could not be completely decanted, 50-100mL remained, in which the precipiate was dispersed.
Up to this point I had assumed the experiment was progressing succesfully, however the issue remains in the attempting to re-dissolve the alks. I found that (despite whatever quantity of vinegar was added), the VAST majority of the precipitate remained in solution. The solution was shaken vigorously, left to stand for several hours, further diluted with vinegar, however nothing succeeded in dissolving what appeared to be the vast majority of the precipitate.
The photos provided in this tek are still very similar to what I experienced, however the quantity of waste "undissolved plant matter" that was described, seemed to be all (if not the majority) of the precipitate itself.
The addition of the vinegar DID cause a visible change to the solution, however this was noticed as a slight change in colour of both the solution and precipitate - definitely NOT as a significant reduction in the volume of precipitate present.
On assuming that at least some alks should now be in solution, the solution was filtered, giving a perfectly clear, yellow solution. [The solid material collected on the filter paper first resembled a grey mud, which dried overnight to yield flakes of dark, brittle material that were insoluble in both vinegar and ethanol (approx. 1g).] The solution was then precipitated with 10% NaOH, which successfully caused the precipitation of a significant quantity of material (as described in the tek, however this precipitate was clearly darker in colour than that described herein). The solution was allowed to settle, decanted, and then washed in the described manner 4 times. The remaining mixture was then dried in a glass baking tray to yield 0.9g of dark-brown semi-crystalline material.
Not only is the resultant material clearly much darker in colour than that described here, but it will also not dissolve in either vinegar or pure ethanol.....
Personally I can't see what could have gone wrong here, except for the possibility that the caapi itself may be juvenile and contain little to no alks (?). But this still doesn't explain why I was able to precipitate out some material on the second attempt (via the addition of NaOH), that now refuses to dissolve in ethanol or vinegar.....
Any ideas on what is going on here?... Should i bother testing the material for activity, or is this a foolish waste of time?
Any thoughts/comments you could provide would be much appreciated. Really confused :S
