After a break I am into extracting harmine and harmaline from syrian rue again.
The seed I bought where whole.
The first kilo I made into 1,5 liter concentrate to drink.

For the second kilo I just wanted the harmaline and harmine.
With the second kilo I came upp with an idea.


Atfer the first boil I decided to use my slow juicer to crush the seeds.
I learned before that putting them through the juicer after freezing and thowing was a bit to rough for the machine.
So, After the first boil the seeds where soft and got crushed very nice.


I kept the first pull separate from the second and third.
Only the second and third pull where with crushed seed.
The second and third left me with a messy filtering proces.

After filtering reducing and filtering again I finally filtered through a buchner with lab filtration paper and basified the lot.
Results.

1 pull, uncrushed seeds, 28 grams
2 and 3 crushed 22 grams

This does not say a lot.
I know the consencus is that powdered seeds/crushed seeds will bring a higher yield.
I really dont like the mess of powdered/crushed seeds.

anyway.
I slow juicer is a nice tool to use

Are you saying that the yield from boiling/ basing /pulling on whole seeds was higher than crushed?

I'm sorry, I'm having a hard time following, i don't know much about harmalas extraction. So you performed that process, boiled, based, then pulled with a solvent, and that gave you 20plus grams of free base, then you crushed the same seeds, boiled again, based that solution and pulled another 20plus? I'm confused. Or two seperate batches?

Not really, because the actives are in the husk (shell) of the seeds.

As i understand it, the slow juicer squuzes the mushy rue seeds?
That's not a bad idea actually if you don'T want to waste anything, i guess
