Xa,
95% ethanol, with a pinch of citric acid, is highly efficient at extracting harmalas from powdered Syrian Rue seeds. I'm just about to finish my first Whiterasta tek...
I also have some caapi leaf, and wonder if the issue is alcohol struggling to penetrate the actual leaf structure, and liberate the harmalas? They're tough as hell, and I guess you haven't gotten close to powdering them?
In which case, a long water boil is probably necessary... I even freeze/thawed mine last time I extracted them, to help loosen them up.
Also, 10g leaf will only yield 1-2%: 100-200mg harmalas, which will be almost invisible in anything other than a very small amount of concentrated solution...
If it was me, I'd probably have started with at least 100g leaf to make it worthwhile.
“I sometimes marvel at how far I’ve come - blissful, even, in the knowledge that I am slowly becoming a well-evolved human being - only to have the illusion shattered by an episode of bad behaviour that contradicts the new and reinforces the old. At these junctures of self-reflection, I ask the question: “are all my years of hard work unraveling before my eyes, or am I just having an episode?” For the sake of personal growth and the pursuit of equanimity, I choose the latter and accept that, on this journey of evolution, I may not encounter just one bad day, but a group of many.”
