..A. floribunda may be as variable as obtusifolia, meaning that at certain times or in individual plants their could be more of less active tryptamines than dmt..
..but also i would suggest extraction would be more efficient with methanol or ethanol with dilute acid..
there is evidence of acacia alkaloids reacting with hydrochloric acid (changing them) and PH 4 is too low..6 would be better,
i would suggest acetic or citric acid..
..and lastly basic PH above 12 can cause possible reactions, or lead to unsatisfactory results...

ps. if you're not sure it's floribunda, you never know what you've got, but it's probably less active than unsafe..could easily be misidentified for different species

thanks for your feedback nen888, I will take your advice on the citric/ acetic acid as this would have been my next attempt. I would expect that overall the PH would not have dropped as low as PH4 though, as when mixed with the fresh bark, this would have reduced quite allot. usually the level sits around 6 or 7 in the process of being cooked, due to evaporation, dilution etc? im not too sure, correct me if i'm wrong (but the ph always seems to neutralise during the acid cook). I have had my doubts with sodium hydroxide basing above 13, as it always seems to push over regardless of my attempt of keeping it below 13. so i'll keep this in mind next time also.
I will get some pictures of the tree in question, as like mentioned am not 100% sure that this is floribunda, an ID would help.
Less active then unsafe sounds good. thanks again for ur feedback.

and while i've got you, your suggesting methanol/ ethanol as an alternative extract solvent obviously yeah?

..i would say that the extract may contain impurities, and would suggest also reX..
i recommend reading entheogenic effects of NMT
particularly p.2, & also question about my acacia spice..suggest alcohol plus dilute acid for extraction (weak sulphuric also possible apparently)
