harmala solubility in acetic acid

[concombres]

I extracted 75g caapi & ended up with ~600mg very light tan, almost white, fluffy powder.
I assumed after the multiple acidifications & basing, along with 5 water washes what i had was relatively pure harmala alkaloids.

Upon dissolving the 600mg in 8ml 5% distilled white vinegar, there seems to be a fair amount of precipitate clouding the solution & sinking to the bottom of the vial.
The liquid glows bright green under blacklight.

Is it possible that the precipitate is harmalas & 8ml is not enough to fully dissolve the amount of harmalas mixed in?
The precipitating impurities look to be a decent percentage of my yeilds even after multiple cleanups.

I would say so yeah.

Why dont you filter your tincture, then try to dissolve whatever is left on the filter in more acetic acid?

If it dissolves, its probably harmalas and you just hadnt added enough, and you can put together with the rest of the filtered tincture. If it doesnt dissolve, its probably some impurity and can be discarded.

You can use warm acetic acid to increase solubility, just in case some of the impurities are somehow 'trapping' harmalas inside and preventing them from dissolving.

I mixed the tincture into a shotglass of clean vinegar, surprisingly, the initial color of the tincture didnt change at all, even with a 5x increase in volume.
Its the same color as a reduced caapi brew (dark yellow, appears to be brown until light is passes thru it close up)

After it settles another couple hours if there is still a large amount of precip i'll run it thru a filter & try to redissolve the gunk in hot vinegar.
