phytochemical studies:

* Plants for medicines CSIRO 1990.

In this book there is a reference to a field alkaloid test of the phyllodes that gave a strongly positive result, indicating that at least in this specimen contain reasonable amounts of alkaloids. There are no further references and no indication that the alkaloids were isolated or tested in anyway.

* Authors studies I saw, through a friend a document that was a list of acacias and their reported alkaloids, it was apparently taken from an e-mail and there did not appear to be any further references, though it seems to have been some sort of academic or research paper. In this paper acacia sophorae was listed, and reported to contain DMT, tetra-hydro-B-carboline and I think N-methyl tryptamine, as well as N-cinnamoylhistamine and another histamine alkaloid. Unfortunately I have not been able to get a copy of this document or find out any more about where the information is from.
It was unclear in the paper wether the tryptamine and B-carboline alkaloids were in fact isolated from the same plant material as the histamine alkaloids, as they were on two seperate lines. Or wether the phyllodes yielded the same alkaloids as the bark that I can recall. From memory the report said that about 0.67% & 0.15% yield were obtained from the bark and the phyllodes respectively, as % of dry weight.

More recently I have heard that these findings were based on plant material collected by the roadside in Los Angeles, California, where this species is apparently naturalised.
