Here is some good info from the article if you dont have the time to go through all of it right now..

"The alkaloids until
now found in P. arundinacea and P. aquatica are:

* N-methyltryptamine (NW)
* 5-methoxy-N-methyltryptamine (5-MeO-DMT)
* N,N-dimethyltryptamine (DMT)
* 5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT)
* 5-hydroxy-N,N-dimethyltryptamine (Bufotenine, 5-OH-DMT)
* 5-methyl-tryptamine
* 5-methoxy-tryptamine
* 2-methyl-1,2,3,4-tetrahydro-8-carboline (MTHC), not found in P.
aquatica
* 2-meth 1-6-methox -1 2 3 4-tetrahydro-ß-carboline (MMTHC
* 2-methyl-6-methoxy-1,2,3,4-tetrahydro-ß-carboline (MMTHC)
* 2,9-dimethyl-6-methoxy-1,2,3,4-tetrahydro-ß-carboline (DMTHC)
* Gramine
* 7-methoxy-gramine
* 5,7-dimethoxy-gramine
* Hordenine

Some of the above-mentioned compounds, such as N-methyl-tryptamine,
5-methyltryptamine, 7-methoxy-gramine etc. are contained in the two species
only in trace amount and they seem to be present exclusively in particular
growing stages, probably as a part of the biosynthetical pathways of other
indole alkaloids [MULVENA et al., 1983]. The ß-carbolines are also found in
the two Phalaris in very low concentration, at most 5% of the indole
alkaloids total amount, that is 0.0003% of the dry weight [AUDETTE et al.,
1969; 1970; FRAHN & O'KEEFE, 1971; GANDER et al., 1976. VIJAYANAGAR et al.,
1975]. Such an unfavorable ratio of B-carbolines/indolalkylamines makes
improbable (but maybe not impossible, particularly for some strains) the
occurrence of the pharmacological conditions for carrying out an
"ayahuasca-like effect" with only the Phalaris plants.

On the other hand the concentration of the other indole alkaloids, among
which the psychoactive DMT and 5-MeO-DMT, is very variable. This
variability, referred to both the absolute amount and the mutual
relationship between the alkaloids, is influenced by many and often
interacting factors."
