A. floribunda tops [harv. Apr.] yielded 0.18% alkaloids, consisting
mostly of tryptamine, with traces of phenethylamine; flowers [harv. Sep.]
yielded 1.18% alkaloids [0.82% from an undated harvest], consisting of
+- equal quantities of tryptamine and phenethylamine (White 1944c); flowers [harv. Oct.] yielded 0.15-0.98% alkaloids; leaves yielded 0.07-0.08%
alkaloids; stems yielded 0.04-0.19% alkaloids; stems and leaves combined
yielded 0.06-0.16% alkaloids (White 1944a); bark has yielded traces of
an alkaloid that was not identifi ed (White 1951). It may be that the techniques used by White were not good for identifying DMT, as this commonly cultivated species has recently been found to be a good source
of that alkaloid. Using TLC/GCMS, leaves were found to contain mostly DMT [usually less than 0.1%]; bark yielded up to c.1% alkaloids, with
0.3-0.5% DMT, slightly less NMT, and small amounts of tryptamine, harman and norharman (Jeremy 2007).
