Probably not the most interesting thing but there is mentioning of iboga alkaloids and lots of plants figured maybe someone would want this?

Damn, that first paper is quite the find, thank you! It will take me a while to get through it. No doubt, the Tabernaemontana genus is a huge untapped reservoir of medicinal and psychotropic alkaloids.

Looks like one of the old Rosetta Folios offerings. Thanks for that!
