From what i read the alk content is less than 0,1%

and is mostly not even dmt but other tryptamines.
I think even attempting it would be a waste of plant ant time. Given the fact MHRB can yield up to 2% nearly 20 times as much.
Quote:L. bicolor var. japonica from Japan has yielded tryptamine alkaloids (0.068-0.106% crude alkaloids from leaf, 0.206% in root-bark) - leaves contained DMT (major alkaloid - 0.25% in one test), 5-MeO-DMT, 5-OH-DMT and 0.035% lespedamine (1-MeO-DMT - possibly active by smoking)
You could rather go for any acacia (even the ones with active leaves) or MH
