So alot of folk have been using IPA soaks of caapi leaf, then using this to infuse herbs.
It has been mentioned that this is not particularly efficient.

Would an a/b on the leaf be better at getting a more effective extraction?

If so, what would folks recommend using in order to dissolve said harmalas for infusion post extraction.

I took 75% iso and dissolved pure harmalas in it within 2 minutes completely. Problem solved. Add some water to your iso if your that worried people.

Freebase?
Justine tells me Ethanol works also.

Grind leaves, do a few boils on them with an acid. Strain the material. Do a base addition, allow for precipitate to settle. Filter and redissolve into acidic water. If the water is still filthy use naptha to defat. Remove defat layer, basify and collect.

Is what I would try, although, I'm not sure of the concentrations of goodies in leaves, it might not even be worth it.

The last time I did an alcohol soak on caapi, I used methanol and did two, 1 month soaks.

I did an A/B on the plant matter afterwards and didn't get anything out.

I don't believe that one soak is enough to get all of the goodies, but 2 soaks seems to do the trick.

I assume it is worth it as apparently folk have been doing IPA soaks on leaf with success. I know vine would be preferable to extract from.
