phytochemical studies:

* Alkaloids of acacia N,N-dimethyltryptamine in a. phlebophylla Rovelli & Vaugan, Aust J Chem #20: 1299-1300, 1967.

In this study 12 kg of dried plant tops were extracted after giving strong positive tests for alkaloids in the field. About 40 g of alkaloids were obtained, a yield of 0.3% of dry weight. Analysis found the alkaloidal fraction to consist of only N,N-dimethyltryptamine with no other bases.

* Ayahuasca Analogues, Jonathon Ott, 1994.

On pg 63 there are two accounts of the use of a. phlebophylla phyllodes, combined with b-carboline containing syrian rue (peganum harmala) seeds, as a source of DMT for an ‘ayahuacsa’ analogue. In the second case it was found that 20 g of a. phlebophylla phyllodes contained enough alkaloids to elicit an entheogenic experience when combined with the MAO inhibiting alkaloids present in syrian rue seeds when taken orally.

I checked out acacia phlebophylla in it’s natural habitat, exposed granite slopes of Mt Buffalo Victoria. A geologist friend informed me that granite and sandstone tend to have a very similar chemical makeup, and acacia obtusifolia seems to quite like similar exposed granite or sandstone at a higher altitude, 800 to over 1200 m, though is not restricted to this.
A. phlebophylla phyllodes have similar texture and red granular margins as a. obtusifolia, and the very young growth is very similar. If the very immature shoots of either of these species is ‘toasted’ with a heat source a strong and distinctive smell due to the alkaloids is noticed, it seems that there is quite a concentration in this new growth. The reported content for the foliage is 0.3% alkaloids of the dry weight, but I would say that the content in this new growth is much higher. See acacia obtusifolia section for a report on smoking these dried tips.
A group of us tried an acacia-uasca brew using syrian rue (peganum harmala) seeds, and in my, and one others, case 20g of acacia phlebophylla phyllodes (per person) were used as the source of tryptamine alkaloids. I used the same amount of syrian rue (@ 3.5 g of ground seeds) as my previous time. All of us felt a definite and quite strong effect from the brew. Other people used alkaloids extracted from acacia obtusifolia as admixture to the syrian rue.
I took the syrian rue first, extracted in lemon juice/ water, over about 1/2 hr. Then when I felt the first effects from that, I took the acacia phlebophylla, ground and extracted in the same way as the syrian rue. I felt the first effects quite rapidly, closed eye visual effects after only about what seemed like 15-20 mins...... leading on to a pretty intense and extremely visual peak somewhere over the next hour....I definetly felt a bit more pinned to the floor, a bit harder on my body than last....not necesarily that bad, but I was trying to stay a bit aware of how everyone else was doing, as only two of us had previously tried this.
I think maybe it was the a. phlebophylla that caused a heavier body feeling, the phyllodes are pretty astringent, and the extract was not so easy to drink. Previously I had used freebase alkaloids dissolved in lemon juice/ water, which makes a relatively clean beveridge, possibly a bit easier for the body to deal with. Or the syrian rue may have had a stronger effect. I fast before I try an acacia-uasca brew, and generally I don’t get too nauseous. Others were nauseous and sick, but that didn’t necesarily detract anything from the experience for them.
The whole experience lasted about 4 hours, at least by that stage we were pretty much all able to walk around.....it was pretty hard to believe how the time had passed. The experience was generally of a similar nature to when I had tried syrian rue with alkaloids extracted from acacia obtusifolia.
