phytochemical studies:

* Study of the composition of the root bark of the Thoughtful Tree, Liu et al, Chemistry (Chinese Chemical Soc, Taiwan) #1:15-16, 1977.

Root bark of this species was found to contain some %2.58 total alakloid, of which %55.25 was reported as N-methyltryptamine, and %44.75 reported as N,N-dimethyltryptamine. Notes that it has a history of use in Traditional Chinese Medicine for fever, inflammation and for diseases of the blood. Currently the highest specific record of N,N-dimethyltryptamine content from any plant material published ever, about %1.15 total of DMT.

* N-methylated tryptamines and other constituents of Acacia confusa of Hong Kong, Arthur et al, Aust J Chem, #20:811-13, 1967.

Stems reported to contain %0.04 N-methyltryptamine, %0.01 N,N-dimethyltryptamine. No alkaloid detected in phyllodes.

* Neurolathryogen, a-amino-B-oxalylaminopropionic acid (ODAP) in legume seeds, Quereshi et al, Phytochemistry, #16:477-79, 1977.

Reports the seeds as containing the toxic amino acid ODAP, which can cause neurological damage to humans and animals that consume it, causing paralysis and possibly death. Only known from extra-Australian species of Acacia, so far.
