So, I've been looking all ovrr the place and I've only found one site (Erowid) that had anything on Caapi leaf alkaloid content. I've read plenty of speculation but does anyone have any tests that state which harmala alks sre found in the leaves. Erowid says Harmla and TTH and others on this site have mentioned TTH only.

Under the wiki, botanicals. There is a lot of information about alkaloids.

This page says "Alkaloids are present in all parts of the plant."

"Harmine, 0.31-8.43%[2]
Harmaline, 0.03-0.83%[2]
Tetrahydroharmine, 0.05-2.94%[2]"

Trout's notes on ayahuasca featured in erowid is very reliable source for this info too, maybe thats the erowid link you meant?
